66955885e2 Make use of kvmalloc if available and fix vmem_alloc implementation
This patch implements use of kvmalloc for GFP_KERNEL allocations, which
may increase performance if the allocator is able to allocate physical
memory, if kvmalloc is available as a public kernel interface (since
v4.12). Otherwise it will simply fall back to virtual memory (vmalloc).

Also fix vmem_alloc implementation which can lead to slow allocations
since the first attempt with kmalloc does not make use of the noretry
flag but tells the linux kernel to retry several times before it fails.

Fix zpool create -o <property> error message
When `zpool create -o <property>` is run without root permissions
and the pool property requested is not specifically enumerated in
zpool_valid_proplist().  Then an incorrect error message referring
to an invalid property is printed rather than the expected permission
denied error.

Specifying a pool property at create time should be handled the same
way as filesystem properties in zfs_valid_proplist().  There should
not be default zfs_error_aux() set for properties which are not
listed.

c5ebfbbe19 Reorganize zpool(8) man page into sections
Moved subcommand topics into individual manpages. Reordered and 
grouped the list of subcommands by topic.

Moved concepts overview to `zpoolconcepts.8` and the long list of
available pool properties to `zpoolprops.8`.

Internal cross-references copied from `zpool.8` needed to be 
converted to `.Xr` external references to new subcommand manual 
pages.

Move `autotrim` into lexical order, autotrim tacked onto the end
of a list. Now it is in alphabetical order.

Clarify attach/detach description. Description was too specific to
command syntax. Overview clarifies reason for attaching or detaching
a device.

Clarify replace description, don't refer to subcommand arguments.

Clarify split command description, say what split actually does and
why you'd want to do it.

Clarify description of upgrade, and simplify the zpool.8 wording of
the zpool-upgrade(8) description.

Clarify description of import, detail what zpool-import(8) actually 
does.

Add appropriate SEE ALSO sections. Divided zpool subcommand manual 
pages need their own SEE ALSO sections. Also modified fsck.zfs.8 
to point directly to zfs-scrub.8 and zed.8.in to include a direct
reference to zfs-events.8

870fc32fc9 Reorganize zfs(8) man page into sections
Most subcommands got their own manpages (e.g. create). Some related
commands grouped into a single manpage and symlinks created (e.g. set, 
get, and inherit). I did this when topics were either too short to 
warrant their own file or so interrelated that a user would want to
refer between commands in the same file.

Corrected .Sx internal references to .Xr cross refs; lots of .Sx 
references from when text was all in zfs.8 needed to be changed to 
.Xr zfs-$SUBCOMMAND 8 cross references.

Divided subcommand list in zfs(8) into sections of related 
functionality. This required writing new descriptions for some 
commands.

Preserved ".Os Linux", `.Os` macro parsing behavior differs between 
mandoc from the "BSD" mandoc package (available on Ubuntu) and man 
from Ubuntu's man-db package, which calls groff to format the manpages.

Groff handles the `.Os` macro differently and wrongly, defaulting 
it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of
getting the default from `uname`.

A future set of changes will introduce build-time preprocessing of
manpages for platform-specific documentation and can insert the
correct operating system name.

Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man
pages needed their own SEE ALSO sections pointing to related
subcommands and, in some cases, documentation from other packages
(e.g. zfs-share.8).

Linux compat: Minimum kernel version 3.10
Increase the minimum supported kernel version from 2.6.32 to 3.10.
This removes support for the following Linux enterprise distributions.

    Distribution     | Kernel | End of Life
    ---------------- | ------ | -------------
    Ubuntu 12.04 LTS | 3.2    | Apr 28, 2017
    SLES 11          | 3.0    | Mar 32, 2019
    RHEL / CentOS 6  | 2.6.32 | Nov 30, 2020

The following changes were made as part of removing support.

* Updated `configure` to enforce a minimum kernel version as
  specified in the META file (Linux-Minimum: 3.10).

    configure: error:
        *** Cannot build against kernel version 2.6.32.
        *** The minimum supported kernel version is 3.10.

* Removed all `configure` kABI checks and matching C code for
  interfaces which solely predate the Linux 3.10 kernel.

* Updated all `configure` kABI checks to fail when an interface is
  missing which was in the 3.10 kernel up to the latest 5.1 kernel.
  Removed the HAVE_* preprocessor defines for these checks and
  updated the code to unconditionally use the verified interface.

* Inverted the detection logic in several kABI checks to match
  the new interface as it appears in 3.10 and newer and not the
  legacy interface.

* Consolidated the following checks in to individual files. Due
  the large number of changes in the checks it made sense to handle
  this now.  It would be desirable to group other related checks in
  the same fashion, but this as left as future work.

  - config/kernel-blkdev.m4 - Block device kABI checks
  - config/kernel-blk-queue.m4 - Block queue kABI checks
  - config/kernel-bio.m4 - Bio interface kABI checks

* Removed the kABI checks for sops->nr_cached_objects() and
  sops->free_cached_objects().  These interfaces are currently unused.

5a6ac4cffc Remove zpl_revalidate
This patch removes the need for zpl_revalidate altogether.

There were 3 main reasons why we used d_revalidate:

1. periodic automounted snapshots umount deferral
2. negative dentries created before snapshot rollback
3. stale inodes referenced by dentry cache after snapshot rollback

Periodic snapshots deferral solution introduces zfs_exit_fs function,
which is called as a part of ZFS_EXIT(zfsvfs_t) macro.

Negative dentries and stale inodes are solved by flushing the dcache
for the particular dataset on zfs_resume_fs call.

This patch also removes now unused HAVE_S_D_OP configure test.

f15d6a5457 Improve logging of 128KB writes
Before my ZIL space optimization few years ago 128KB writes were logged
as two 64KB+ records in two 128KB log blocks.  After that change it
became ~127KB+/1KB+ in two 128KB log blocks to free space in the second
block for another record.  Unfortunately in case of 128KB only writes,
when space in the second block remained unused, that change increased
write latency by unbalancing checksum computation and write times
between parallel threads.  It also didn't help with SLOG space
efficiency in that case.

This change introduces new 68KB log block size, used for both writes
below 67KB and 128KB-sharp writes.  Writes of 68-127KB are still using
one 128KB block to not increase processing overhead.  Writes above
131KB are still using full 128KB blocks, since possible saving there
is small.  Mixed loads will likely also fall back to previous 128KB,
since code uses maximum of the last 16 requested block sizes.

ae38e00968 Add tracepoints for taskq entry lifetime events
This adds some new DTRACE_PROBE* endpoints so that we can observe taskq
latencies on a system. Additionally, a new "taskqlatency.bt" script is
added to do this observation via "bpftrace". Lastly, a "zfs-trace.sh"
script is added to wrap "bpftrace" with the proper options required to
run and use "taskqlatency.bt".

For example, with these changes in place, a user can run the following:

    $ cd ./contrib/bpftrace
    $ sudo ./zfs-trace.sh taskqlatency.bt
    Attaching 6 probes...
    ^C

e5d1c27e30 Enable use of DTRACE_PROBE* macros in "spl" module
This change modifies some of the infrastructure for enabling the use of
the DTRACE_PROBE* macros, such that we can use tehm in the "spl" module.

Currently, when the DTRACE_PROBE* macros are used, they get expanded to
create new functions, and these dynamically generated functions become
part of the "zfs" module.

Since the "spl" module does not depend on the "zfs" module, the use of
DTRACE_PROBE* in the "spl" module would result in undefined symbols
being used in the "spl" module. Specifically, DTRACE_PROBE* would turn
into a function call, and the function being called would be a symbol
only contained in the "zfs" module; which results in a linker and/or
runtime error.

Thus, this change adds the necessary logic to the "spl" module, to
mirror the tracing functionality available to the "zfs" module. After
this change, we'll have a "trace_zfs.h" header file which defines the
probes available only to the "zfs" module, and a "trace_spl.h" header
file which defines the probes available only to the "spl" module.

b4238327b4 Fix incremental recursive encrypted receive
Currently, incremental recursive encrypted receives fail to work
for any snapshot after the first. The reason for this is because
the check in zfs_setup_cmdline_props() did not properly realize
that when the user attempts to use '-x encryption' in this
situation, they are not really overriding the existing encryption
property and instead are attempting to prevent it from changing.
This resulted in an error message stating: "encryption property
'encryption' cannot be set or excluded for raw or incremental
streams".

This problem is fixed by updating the logic to expect this use
case.

Linux 4.14, 4.19, 5.0+ compat: SIMD save/restore
Contrary to initial testing we cannot rely on these kernels to
invalidate the per-cpu FPU state and restore the FPU registers.
Nor can we guarantee that the kernel won't modify the FPU state
which we saved in the task struck.

Therefore, the kfpu_begin() and kfpu_end() functions have been
updated to save and restore the FPU state using our own dedicated
per-cpu FPU state variables.

This has the additional advantage of allowing us to use the FPU
again in user threads.  So we remove the code which was added to
use task queues to ensure some functions ran in kernel threads.
