db4fc559cc Linux 6.7 compat: use inode atime/mtime accessors
6.6 made i_ctime inaccessible; 6.7 has done the same for i_atime and
i_mtime. This extends the method used for ctime in b37f29341 to atime
and mtime as well.

00f40961e0 Linux 6.7 compat: simplify current_time() check
6.7 changed the names of the time members in struct inode, so we can't
assign back to it because we don't know its name. In practice this
doesn't matter though - if we're missing current_time(), then we must be
on <4.9, and we know our fallback will need to return timespec.

compact: workaround for GPL-only symbols on riscv from Linux 6.2
Since Linux 6.2, the implementation of flush_dcache_page on riscv
references GPL-only symbol `PageHuge`, breaking the build of zfs.

This patch uses existing mechanism to override flush_dcache_page,
removing the call to `PageHuge`. According to comments in kernel,
it is only used to do some check against HugeTLB pages, which only
exist in userspace. ZFS uses flush_dcache_page only on kernel pages,
thus this patch will not introduce any behaviour change.

rpm: Fix make rpm on Debian/Ubuntu
The recent patch to change the bash completion install location based
on the Distribution, ignored that it should still be possible to
create RPMs on Debian derived systems. Additionally `make deb` itself
creates RPMs and converts them via `alien`.

This patch adds the bashcompletiondir variable to the rpm defines and
uses this for the location, where to get the bash completion file.

It still changes the location on Debian/Ubuntu systems in the final
packages from /etc/bash_completion.d to
/usr/share/bash-completion/completions

e69ade32e1 contrib: bash_completion.d: make install destination vendor dependent
Certain Linux distributions (Debian/Ubuntu at least) expect
bash-completion snippets to be installed in
/usr/share/bash-completion/completions instead of
/etc/bash_completion.d.

This patch sets the bashcompletiondir variable based on the vendor,
inspired by similar settings for initdir and initconfdir.

It seems that commit 612b8dff5b
caused the file to be installed in the first-place (thus the error
when building debian packages only became apparent when testing a
2.2.0-rc4 build)

The change only sets the variable in Makefile context - the
rpm/zfs.spec.in file has the path hardcoded as
%{_sysconfdir}/bash_completion.d/zfs, but since running
```
./configure --sysconfdir=/myetc  ; make rpm
```
also results in all relevant files to be installed in /etc instead of
/myetc I assume this can remain as is.

b37f29341b Linux 6.6 compat: use inode_get/set_ctime*(...)
In Linux commit 13bc24457850583a2e7203ded05b7209ab4bc5ef, direct access
to the i_ctime member of struct inode was removed. The new approach is
to use accessor methods that exclusively handle passing the timestamp
around by value. This change adds new tests for each of these functions
and introduces zpl_* equivalents in include/os/linux/zfs/sys/zpl.h. In
where the inode_get/set_ctime*() functions exist, these zpl_* calls will
be mapped to the new functions. On older kernels, these macros just wrap
direct-access calls. The code that operated on an address of ip->i_ctime
to call ZFS_TIME_DECODE() now will take a local copy using
zpl_inode_get_ctime(), and then pass the address of the local copy when
performing the ZFS_TIME_DECODE() call, in all cases, rather than
directly accessing the member.

Linux 6.5 compat: replace generic_file_splice_read with filemap_splice_read

of filemap_splice_read. Add an autoconf test for filemap_splice_read and

change removes the ITER_* macros that OpenZFS doesn't use from being
tested in config/kernel-vfs-iov_iter.m4. The removal of ITER_PIPE was
causing the test to fail, which also affected the code responsible for
setting the .splice_read handler, above. That behavior caused run-time
panics on Linux 6.5.

Linux 6.5 compat: blkdev changes
Multiple changes to the blkdev API were introduced in Linux 6.5. This
includes passing (void* holder) to blkdev_put, adding a new
blk_holder_ops* arg to blkdev_get_by_path, adding a new blk_mode_t type
that replaces uses of fmode_t, and removing an argument from the release
handler on block_device_operations that we weren't using. The open
function definition has also changed to take gendisk* and blk_mode_t, so
update it accordingly, too.

Implement local wrappers for blkdev_get_by_path() and
vdev_blkdev_put() so that the in-line calls are cleaner, and place the
conditionally-compiled implementation details inside of both of these
local wrappers. Both calls are exclusively used within vdev_disk.c, at
this time.

Add blk_mode_is_open_write() to test FMODE_WRITE / BLK_OPEN_WRITE
The wrapper function is now used for testing using the appropriate
method for the kernel, whether the open mode is writable or not.

Emphasize fmode_t arg in zvol_release is not used

Workaround for Linux PowerPC GPL-only cpu_has_feature()
Linux since 4.7 makes interface 'cpu_has_feature' to use jump labels on
powerpc if CONFIG_JUMP_LABEL_FEATURE_CHECKS is enabled, in this case
however the inline function references GPL-only symbol
'cpu_feature_keys'.

ZFS currently uses 'cpu_has_feature' either directly or indirectly from
several places; while it is unknown how this issue didn't break ZFS on
64-bit little-endian powerpc, it is known to break ZFS with many Linux
versions on both 32-bit and 64-bit big-endian powerpc.

Until this issue is fixed in Linux, we have to workaround it by
overriding affected inline functions without depending on
'cpu_feature_keys'.

The 22.0 release of the python `packaging` package removed the

This commit replaces the sections of `ax_python_dev.m4` that rely on
`LegacyVersion` with updated implementations from the upstream

Add native-deb* targets to build native Debian packages
In continuation of previous #13451, this commits adds native-deb*
targets for make to build native debian packages. Github workflows
are updated to build and test native Debian packages.

Native packages only build with pre-configured paths (see the
dh_auto_configure section in contrib/debian/rules.in). While
building native packages, paths should not be configured. Initial
config flags e.g. '--enable-debug' are replaced in
contrib/debian/rules.in.

Additional packages on top of existing zfs packages required to
build native packages include debhelper-compat, dh-python, dkms,
po-debconf, python3-all-dev, python3-sphinx.

infrastructure to support idmapped mounts of filesystems mounted 
with an idmapping". Update the OpenZFS accordingly to improve the 
idmapped mount support. 

This pull request contains the following changes:

- xattr setter functions are fixed to take mnt_ns argument. Without
  this, cp -p would fail for an idmapped mount in a user namespace.
- idmap_util is enhanced/fixed for its use in a user ns context.
- One test case added to test idmapped mount in a user ns.

dbf6108b4d zfs_rename: support RENAME_* flags
Implement support for Linux's RENAME_* flags (for renameat2). Aside from
being quite useful for userspace (providing race-free ways to exchange
paths and implement mv --no-clobber), they are used by overlayfs and are
thus required in order to use overlayfs-on-ZFS.

In order for us to represent the new renameat2(2) flags in the ZIL, we
create two new transaction types for the two flags which need
transactional-level support (RENAME_EXCHANGE and RENAME_WHITEOUT).
RENAME_NOREPLACE does not need any ZIL support because we know that if
the operation succeeded before creating the ZIL entry, there was no file
to be clobbered and thus it can be treated as a regular TX_RENAME.

ff7a0a108f Linux: Remove ZFS_AC_KERNEL_SRC_MODULE_PARAM_CALL_CONST autotools check
On older kernels, the definition for `module_param_call()` typecasts
function pointers to `(void *)`, which triggers -Werror, causing the
check to return false when it should return true.

Fixing this breaks the build process on some older kernels because they
define a `__check_old_set_param()` function in their headers that checks
for a non-constified `->set()`. We workaround that through the c
preprocessor by defining `__check_old_set_param(set)` to `(set)`, which
prevents the build failures.

However, it is now apparent that all kernels that we support have
adopted the GRSecurity change, so there is no need to have an explicit
autotools check for it anymore. We therefore remove the autotools check,
while adding the workaround to our headers for the build time
non-constified `->set()` check done by older kernel headers.

Cleanup: Switch to strlcpy from strncpy
Coverity found a bug in `zfs_secpolicy_create_clone()` where it is
possible for us to pass an unterminated string when `zfs_get_parent()`
returns an error. Upon inspection, it is clear that using `strlcpy()`
would have avoided this issue.

Looking at the codebase, there are a number of other uses of `strncpy()`
that are unsafe and even when it is used safely, switching to
`strlcpy()` would make the code more readable. Therefore, we switch all
instances where we use `strncpy()` to use `strlcpy()`.

Unfortunately, we do not portably have access to `strlcpy()` in
tests/zfs-tests/cmd/zfs_diff-socket.c because it does not link to
libspl. Modifying the appropriate Makefile.am to try to link to it
resulted in an error from the naming choice used in the file. Trying to
disable the check on the file did not work on FreeBSD because Clang
ignores `#undef` when a definition is provided by `-Dstrncpy(...)=...`.
We workaround that by explictly including the C file from libspl into
the test. This makes things build correctly everywhere.

We add a deprecation warning to `config/Rules.am` and suppress it on the
remaining `strncpy()` usage. `strlcpy()` is not portably avaliable in
tests/zfs-tests/cmd/zfs_diff-socket.c, so we use `snprintf()` there as a
substitute.

This patch does not tackle the related problem of `strcpy()`, which is
even less safe. Thankfully, a quick inspection found that it is used far
more correctly than strncpy() was used. A quick inspection did not find
any problems with `strcpy()` usage outside of zhack, but it should be
said that I only checked around 90% of them.

Lastly, some of the fields in kstat_t varied in size by 1 depending on
whether they were in userspace or in the kernel. The origin of this
discrepancy appears to be 04a479f706 where
it was made for no apparent reason. It conflicts with the comment on
KSTAT_STRLEN, so we shrink the kernel field sizes to match the userspace
field sizes.

zvol: Support blk-mq for better performance
Add support for the kernel's block multiqueue (blk-mq) interface in
the zvol block driver.  blk-mq creates multiple request queues on
different CPUs rather than having a single request queue.  This can
improve zvol performance with multithreaded reads/writes.

This implementation uses the blk-mq interfaces on 4.13 or newer
kernels.  Building against older kernels will fall back to the
older BIO interfaces.

Note that you must set the `zvol_use_blk_mq` module param to
enable the blk-mq API.  It is disabled by default.

In addition, this commit lets the zvol blk-mq layer process whole
`struct request` IOs at a time, rather than breaking them down
into their individual BIOs.  This reduces dbuf lock contention
and overhead versus the legacy zvol submit_bio() codepath.

	sequential dd to one zvol, 8k volblocksize, no O_DIRECT:

	legacy submit_bio()     292MB/s write  453MB/s read
	this commit             453MB/s write  885MB/s read

It also introduces a new `zvol_blk_mq_chunks_per_thread` module
parameter. This parameter represents how many volblocksize'd chunks
to process per each zvol thread.  It can be used to tune your zvols
for better read vs write performance (higher values favor write,
lower favor read).

Introduce BLAKE3 checksums as an OpenZFS feature
This commit adds BLAKE3 checksums to OpenZFS, it has similar
performance to Edon-R, but without the caveats around the latter.

Homepage of BLAKE3: https://github.com/BLAKE3-team/BLAKE3
Wikipedia: https://en.wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE3

Short description of Wikipedia:

  BLAKE3 is a cryptographic hash function based on Bao and BLAKE2,
  created by Jack O'Connor, Jean-Philippe Aumasson, Samuel Neves, and
  Zooko Wilcox-O'Hearn. It was announced on January 9, 2020, at Real
  World Crypto. BLAKE3 is a single algorithm with many desirable
  features (parallelism, XOF, KDF, PRF and MAC), in contrast to BLAKE
  and BLAKE2, which are algorithm families with multiple variants.
  BLAKE3 has a binary tree structure, so it supports a practically
  unlimited degree of parallelism (both SIMD and multithreading) given
  enough input. The official Rust and C implementations are
  dual-licensed as public domain (CC0) and the Apache License.

Along with adding the BLAKE3 hash into the OpenZFS infrastructure a
new benchmarking file called chksum_bench was introduced.  When read
it reports the speed of the available checksum functions.

On Linux: cat /proc/spl/kstat/zfs/chksum_bench
On FreeBSD: sysctl kstat.zfs.misc.chksum_bench

- 4x assembly for X86-64 (SSE2, SSE4.1, AVX2, AVX512)
- 2x assembly for ARMv8 (NEON converted from SSE2)
- 2x assembly for PPC64-LE (POWER8 converted from SSE2)
- one file for switching between the implementations

Note the PPC64 assembly requires the VSX instruction set and the
kfpu_begin() / kfpu_end() calls on PowerPC were updated accordingly.

Replace EXTRA_DIST with dist_noinst_DATA
The EXTRA_DIST variable is ignored when used in the FALSE conditional
of a Makefile.am.  This results in the `make dist` target omitting
these files from the generated tarball unless CONFIG_USER is defined.
This issue can be avoided by switching to use the dist_noinst_DATA
variable which is handled as expected by autoconf.

This change also adds support for --with-config=dist as an alias
for --with-config=srpm and updates the GitHub workflows to use it.

Fix compiler warnings about zero-length arrays in inline bitops
The compiler appears to be expanding the unused NULL pointer into a
zero-length array via the inline bitops code. When -Werror=array-bounds
is used, this causes a build failure. Recommended solution is allocate
temporary structures, fill with zeros (to avoid uninitialized data use
warnings), and pass the pointer to those to the inline calls.

autoconf: Pretend CONFIG_MODULES is always on
- Unconditionally inject `CONFIG_MODULES` make variable
  and `#define CONFIG_MODULES` to Kbuild in `ZFS_LINUX_COMPILE`
  autoconf function to emulate loadable kernel modules support.
  This allows OpenZFS to perform Linux checks despite
  `CONFIG_MODULES=n` in the actual Linux config.

- Add `ZFS_AC_KERNEL_CONFIG_MODULES` check which encompasses
  the logic from `ZFS_AC_KERNEL_TEST_MODULE` with additional
  diagnostic messages to the user

- Removed `ZFS_AC_KERNEL_TEST_MODULE` as it merely duplicates
  every check in `ZFS_AC_KERNEL_CONFIG_DEFINED`

- Moved `ZFS_AC_MODULE_SYMVERS` after `ZFS_AC_KERNEL_CONFIG_DEFINED`
  so the user has a chance to see the proper diagnostic from the

kbuild: unify modules(_install) for in-tree and external modules

If you attempt to build or install modules ('make modules(_install)'
with CONFIG_MODULES disabled, you will get a clear error message, but
nothing for external module builds.

Factor out the modules and modules_install rules into the common part,
so you will get the same error message when you try to build external
modules with CONFIG_MODULES=n.

Linux optimize access checks when ACL is trivial
Bypass check of ZFS aces if the ACL is trivial. When an ACL is
trivial its permissions are represented by the mode without any
loss of information. In this case, it is safe to convert the
access request into equivalent mode and then pass desired mask
and inode to generic_permission(). This has the added benefit
of also checking whether entries in a POSIX ACL on the file grant
the desired access.

This commit also skips the ACL check on looking up the xattr dir
since such restrictions don't exist in Linux kernel and it makes
xattr lookup behavior inconsistent between SA and file-based
xattrs. We also don't want to perform a POSIX ACL check while
looking up the POSIX ACL if for some reason it is located in
the xattr dir rather than an SA.

Use _Noreturn (C11; GNU89) properly
A function that returns with no value is a different thing from a
function that doesn't return at all.  Those are two orthogonal
concepts, commonly confused.

pthread_create(3) expects a pointer to a start routine that has a
very precise prototype:

    void *(*start_routine)(void *);

However, other thread functions, such as kernel ones, expect:

    void (*start_routine)(void *);

Providing a different one is incorrect, and has only been working
because the ABIs happen to produce a compatible function.

We should use '_Noreturn void', since it's the natural type, and
then provide a '_Noreturn void *' wrapper for pthread functions.

For consistency, replace most cases of __NORETURN or
__attribute__((noreturn)) by _Noreturn.  _Noreturn is understood
by -std=gnu89, so it should be safe to use everywhere.

Fix Linux kernel directories detection
Most modern Linux distributions have separate locations for bare
source and prebuilt ("build") files. Additionally, there are `source`
and `build` symlinks in `/lib/modules/$(KERNEL_VERSION)` pointing to
them. The order of directory search is now:
- `configure` command line values if both `--with-linux` and
  `--with-linux-obj` were defined
- If only `--with-linux` was defined, `--with-linux-obj` is assumed
  to have the same value as `--with-linux`
- If neither `--with-linux` nor `--with-linux-obj` were defined
  autodetection is used:
  - `/lib/modules/$(uname -r)/{source,build}` respectively, if exist
  - The first directory in `/lib/modules` with the highest version
    number according to `sort -V` which contains `source` and `build`
    symlinks/directories
  - The first directory matching `/usr/src/kernels/*` and
    `/usr/src/linux-*` with the highest version number according to
    `sort -V`. Here the source and prebuilt directories are assumed
    to be the same.

b66140c6ad Add support for $KERNEL_{CC,LD,LLVM} variables
Currently, $(CC), $(LD), and $(LLVM) variables aren't passed to kbuild
while building modules.  This causes modules to build with the default
GNU GCC toolchain and prevents experimenting with other toolchains such
as CLANG/LLVM.  It can also lead to build failure if the CFLAGS/LDFLAGS
passed are incompatible with gcc/ld.

Pass $KERNEL_CC, $KERNEL_LD, and $KERNEL_LLVM as $(CC), $(LD), and
$(LLVM), respectively, to kbuild for each that is defined in the
environment.  This should take care of the majority of alternative
toolchain use cases.

Linux 5.16 compat: don't use XSTATE_XSAVE to save FPU state
Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach,
so add our own XSAVE{,OPT,S} code and use it for Linux 5.16.

Please note that this differs from previous behavior in that it
won't handle exceptions created by XSAVE an XRSTOR. This is sensible
for three reasons.

 - Exceptions during XSAVE and XRSTOR can only occur if the feature
   is not supported or enabled or the memory operand isn't aligned
   on a 64 byte boundary. If this happens something else went
   terribly wrong, and it may be better to stop execution.

 - Previously we just printed a warning and didn't handle the fault,
   this is arguable for the above reason.

 - All other *SAVE instruction also don't handle exceptions, so this
   at least aligns behavior.

Finally add a test to catch such a regression in the future.

Add --enable-asan and --enable-ubsan switches
`configure` now accepts `--enable-asan` and `--enable-ubsan` switches
which results in passing `-fsanitize=address`
and `-fsanitize=undefined`, respectively, to the compiler. Those
flags are enabled in GitHub workflows for ZTS and zloop. Errors
reported by both instrumentations are corrected, except for:

- Memory leak reporting is (temporarily) suppressed. The cost of
  fixing them is relatively high compared to the gains.

- Checksum computing functions in `module/zcommon/zfs_fletcher*`
  have UBSan errors suppressed. It is completely impractical
  to enforce 64-byte payload alignment there due to performance
  impact.

- There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom
  memory allocator is used there rendering that measure
  unfeasible.

- Memory leaks detection has to be suppressed for `cmd/zvol_id`.
  `zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is
  incompatible with memory leaks detection.

Updated the lz4 decompressor
As an experiment, I stole the lz4 decompressor from
upstream lz4 (1.9.3), and landed it.

Feedback suggested that keeping the vendor lz4 code isolated and
unlinted was probably reasonable, so I lobbed it into its own file.

It also seemed reasonable to put the mostly-untouched* code into
lz4.c proper, and relegate the integrated and ZFS-specific code to
lz4_zfs.c.

1e767532f2 Linux 5.16: The blk-cgroup.h header is where struct blkcg_gq is defined
The definition of struct blkcg_gq was moved into blk-cgroup.h, which is
a header that's been in Linux since 2015. This is used by
vdev_blkg_tryget() in module/os/linux/zfs/vdev_disk.c. Since the kernel
for CentOS 7 and similar-generation releases doesn't have this header,
its inclusion is guarded by a configure test.

d08b99aca0 Linux 5.16: bio_set_dev is no longer a helper macro
This change adds a confiugre check to determine if bio_set_dev is a
helper macro or not. If not, then the attempt to override its internal
call to bio_associate_blkg(), with a macro definition to our own
version, is no longer possible, as the compiler won't use it when
compiling the new inline function replacement implemented in the header.
This change also creates a new vdev_bio_set_dev() function that performs
the same work, and also performs the work implemented in
vdev_bio_associate_blkg(), as it is the only thing calling that function
in our code. Our custom vdev_bio_associate_blkg() is now only compiled
if the bio_set_dev() is a macro in the Linux headers.

Linux 5.13 compat: retry zvol_open() when contended
Due to a possible lock inversion the zvol open call path on Linux
needs to be able to retry in the case where the spa_namespace_lock
cannot be acquired.

For Linux 5.12 an older kernel this was accomplished by returning
-ERESTARTSYS from zvol_open() to request that blkdev_get() drop
the bdev->bd_mutex lock, reaquire it, then call the open callback
again.  However, as of the 5.13 kernel this behavior was removed.

Therefore, for 5.12 and older kernels we preserved the existing
retry logic, but for 5.13 and newer kernels we retry internally in
zvol_open().  This should always succeed except in the case where
a pool's vdev are layed on zvols, in which case it may fail.  To
handle this case vdev_disk_open() has been updated to retry when
opening a device when -ERESTARTSYS is returned.

Linux 5.15 compat: block device readahead
The 5.15 kernel moved the backing_dev_info structure out of
the request queue structure which causes a build failure.

Rather than look in the new location for the BDI we instead
detect this upstream refactoring by the existance of either
the blk_queue_update_readahead() or disk_update_readahead()
functions.  In either case, there's no longer any reason to
manually set the ra_pages value since it will be overridden
with a reasonable default (2x the block size) when
blk_queue_io_opt() is called.

Therefore, we update the compatibility wrapper to do nothing
for 5.9 and newer kernels.  While it's tempting to do the
same for older kernels we want to keep the compatibility
code to preserve the existing behavior.  Removing it would
effectively increase the default readahead to 128k.

Introduce write-mostly sums
wmsum counters are a reduced version of aggsum counters, optimized for
write-mostly scenarios.  They do not provide optimized read functions,
but instead allow much cheaper add function.  The primary usage is
infrequently read statistic counters, not requiring exact precision.

The Linux implementation is directly mapped into percpu_counter KPI.
The FreeBSD implementation is directly mapped into counter(9) KPI.
In user-space due to lack of better implementation mapped to aggsum.

Unfortunately neither Linux percpu_counter nor FreeBSD counter(9)
provide sufficient functionality to completelly replace aggsum, so
it still remains to be used for several hot counters.

Add "compatibility" property for zpool feature sets
Property to allow sets of features to be specified; for compatibility
with specific versions / releases / external systems. Influences
the behavior of 'zpool upgrade' and 'zpool create'. Initial man
page changes and test cases included.

Brief synopsis:

zpool create -o compatibility=off|legacy|file[,file...] pool vdev...

compatibility = off : disable compatibility mode (enable all features)
compatibility = legacy : request that no features be enabled
compatibility = file[,file...] : read features from specified files.
Only features present in *all* files will be enabled on the
resulting pool. Filenames may be absolute, or relative to
/etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc
checked first).

Only affects zpool create, zpool upgrade and zpool status.

ABI changes in libzfs:

* New function "zpool_load_compat" to load and parse compat sets.
* Add "zpool_compat_status_t" typedef for compatibility parse status.
* Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum
* Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum

An initial set of base compatibility sets are included in
cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is
modified to install these in $pkgdatadir/compatibility.d and to
create symbolic links to a reasonable set of aliases.

0e6c493fec cppcheck: integrete cppcheck
In order for cppcheck to perform a proper analysis it needs to be
aware of how the sources are compiled (source files, include
paths/files, extra defines, etc).  All the needed information is
available from the Makefiles and can be leveraged with a generic
cppcheck Makefile target.  So let's add one.

Additional minor changes:

* Removing the cppcheck-suppressions.txt file.  With cppcheck 2.3
  and these changes it appears to no longer be needed.  Some inline
  suppressions were also removed since they appear not to be
  needed.  We can add them back if it turns out they're needed
  for older versions of cppcheck.

* Added the ax_count_cpus m4 macro to detect at configure time how
  many processors are available in order to run multiple cppcheck
  jobs.  This value is also now used as a replacement for nproc
  when executing the kernel interface checks.

* "PHONY =" line moved in to the Rules.am file which is included
  at the top of all Makefile.am's.  This is just convenient becase
  it allows us to use the += syntax to add phony targets.

* One upside of this integration worth mentioning is it now allows
  `make cppcheck` to be run in any directory to check that subtree.

* For the moment, cppcheck is not run against the FreeBSD specific
  kernel sources.  The cppcheck-FreeBSD target will need to be
  implemented and testing on FreeBSD to support this.

Linux 4.18.0-257.el8 compat: blk_alloc_queue()
The CentOS stream 4.18.0-257 kernel appears to have backported
the Linux 5.9 change to make_request_fn and the associated API.
To maintain weak modules compatibility the original symbol was
retained and the new interface blk_alloc_queue_rh() was added.

Unfortunately, blk_alloc_queue() was replaced in the blkdev.h
header by blk_alloc_queue_bh() so there doesn't seem to be a way
to build new kmods against the old interfces.  Even though they
appear to still be available for weak module binding.

To accommodate this a configure check is added for the new _rh()
variant of the function and used if available.  If compatibility
code gets added to the kernel for the original blk_alloc_queue()
interface this should be fine.  OpenZFS will simply continue to
prefer the new interface and only fallback to blk_alloc_queue()
when blk_alloc_queue_rh() isn't available.

Linux 5.10 compat: use iov_iter in uio structure
As of the 5.10 kernel the generic splice compatibility code has been
removed.  All filesystems are now responsible for registering a
->splice_read and ->splice_write callback to support this operation.

The good news is the VFS provided generic_file_splice_read() and
iter_file_splice_write() callbacks can be used provided the ->iter_read
and ->iter_write callback support pipes.  However, this is currently
not the case and only iovecs and bvecs (not pipes) are ever attached
to the uio structure.

This commit changes that by allowing full iov_iter structures to be
attached to uios.  Ever since the 4.9 kernel the iov_iter structure
has supported iovecs, kvecs, bvevs, and pipes so it's desirable to
pass the entire thing when possible.  In conjunction with this the
uio helper functions (i.e uiomove(), uiocopy(), etc) have been
updated to understand the new UIO_ITER type.

Note that using the kernel provided uio_iter interfaces allowed the
existing Linux specific uio handling code to be simplified.  When
there's no longer a need to support kernel's older than 4.9, then
it will be possible to remove the iovec and bvec members from the
uio structure and always use a uio_iter.  Until then we need to
maintain all of the existing types for older kernels.

Some additional refactoring and cleanup was included in this change:

- Added checks to configure to detect available iov_iter interfaces.
  Some are available all the way back to the 3.10 kernel and are used
  when available.  In particular, uio_prefaultpages() now always uses
  iov_iter_fault_in_readable() which is available for all supported
  kernels.

- The unused UIO_USERISPACE type has been removed.  It is no longer
  needed now that the uio_seg enum is platform specific.

- Moved zfs_uio.c from the zcommon.ko module to the Linux specific
  platform code for the zfs.ko module.  This gets it out of libzfs
  where it was never needed and keeps this Linux specific code out
  of the common sources.

- Removed unnecessary O_APPEND handling from zfs_iter_write(), this
  is redundant and O_APPEND is already handled in zfs_write();

Add compatibility for busybox mktemp
Busybox's mktemp requires at least six X's in the template, causing
the current sed --in-place check to fail because the file does not
exist. This change adds additional X's to mktemp templates that do
not already have at least six X's in them.

14c34c3d49 Library ABI tracking with abigail
Provide two make targets: checkabi and storeabi.

storeabi uses libabigail to generate a reference copy of the ABI for the
public libraries.

checkabi compares such a reference to the compiled version, failing if
they are not compatible.  No ABI is generated for libzpool.so, it is
only used by ztest and zdb and not external consumers.
