Inspection of a Ubuntu 14.04 x64 system revealed that the config file
used to build the kernel image differs from the config file used to
build kernel modules by the presence of CONFIG_DEBUG_INFO=y:
This in itself is insufficient to show that the kernel is built with
debuginfo, but a cursory analysis of the debuginfo provided and the
size of the kernel strongly suggests that it was built with
CONFIG_DEBUG_INFO=y while the modules were not. Installing
linux-image-$(uname -r)-dbgsym had no obvious effect on the debuginfo
provided by either the modules or the kernel.
The consequence is that issue reports from distributions such as Ubuntu
and its derivatives build kernel modules without debuginfo contain
nonsensical backtraces. It is therefore desireable to force generation
of debuginfo, so we implement --enable-debuginfo. Since the build system
can build both userspace components and kernel modules, the generic
--enable-debuginfo option will force debuginfo for both. However, it
also supports --enable-debuginfo=kernel and --enable-debuginfo=user for
finer grained control.
Enabling debuginfo for the kernel modules works by injecting
CONFIG_DEBUG_INFO=y into the make environment. This is enables
generation of debuginfo by the kernel build systems on all Linux
kernels, but the build environment is slightly different int hat
CONFIG_DEBUG_INFO has not been in the CPP. Adding -DCONFIG_DEBUG_INFO
would fix that, but it would also cause build failures on kernels where
CONFIG_DEBUG_INFO=y is already set. That would complicate its use in
DKMS environments that support a range of kernels and is therefore
undesireable. We could write a compatibility shim to enable
CONFIG_DEBUG_INFO only when it is explicitly disabled, but we forgo
doing that because it is unnecessary. Nothing in ZoL or the kernel uses
CONFIG_DEBUG_INFO in the CPP at this time and that is unlikely to
change.
Enabling debuginfo for the userspace components is done by injecting -g
into CPPFLAGS. This is not necessary because the build system honors the
environment's CPPFLAGS by appending them to the actual CPPFLAGS used,
but it is supported for consistency.

Linux has read-ahead logic designed to accelerate sequential workloads.
ZFS has its own read-ahead logic called zprefetch that operates on both
ZVOLs and datasets. Having two prefetchers active at the same time can
cause overprefetching, which unnecessarily reduces IOPS performance on
CoW filesystems like ZFS.
Testing shows that entirely disabling the Linux prefetch results in
a significant performance penalty for reads while commensurate benefits
are seen in random writes. It appears that read-ahead benefits are
inversely proportional to random write benefits, and so a single page
of Linux-layer read-ahead appears to offer the middle ground for both
workloads.

In glibc 2.5, makedev(), major(), and minor() are defined in
sys/sysmacros.h. They are also defined in types.h for backward
compatability, but using these definitions triggers a compile warning.
This breaks the ZFS build, as it builds with -Werror.
autoconf email threads indicate these macros may be defined in
sys/mkdev.h in some cases.
This commit adds configure checks to detect where makedev() is defined:
sys/sysmacros.h
sys/mkdev.h
It assumes major() and minor() are defined in the same place.
The libspl types.h then includes
sys/sysmacros.h (preferred) or
sys/mkdev.h (2nd choice)
if one of those defines makedev().
This is done before including the system types.h.
An alternative would be to remove uses of major, minor, and makedev,
instead comparing the st_dev returned from stat64. These configure
checks would then be unnecessary.
This change revealed that __NORETURN was being defined unnecessarily in
libspl/include/sys/sysmacros.h. That definition is removed.
The files in which __NORETURN are used all include types.h, and so all
will get the definition provided by feature_tests.h

In torvalds/linux@a528d35, there are changes to the getattr family of functions,
struct kstat, and the interface of inode_operations .getattr.
The inode_operations .getattr and simple_getattr() interface changed to:
int (*getattr) (const struct path *, struct dentry *, struct kstat *,
u32 request_mask, unsigned int query_flags)
The request_mask argument indicates which field(s) the caller intends to use.
Fields the caller has not specified via request_mask may be set in the returned
struct anyway, but their values may be approximate.
The query_flags argument indicates whether the filesystem must update
the attributes from the backing store.
Currently both fields are ignored. It is possible that getattr-related
functions within zfs could be optimized based on the request_mask.
struct kstat includes new fields:
u32 result_mask; /* What fields the user got */
u64 attributes; /* See STATX_ATTR_* flags */
struct timespec btime; /* File creation time */
Fields attribute and btime are cleared; the result_mask reflects this. These
appear to be optional based on simple_getattr() and vfs_getattr() within the
kernel, which take the same approach.

Background information: This assertion about tx_space_* verifies that we
are not dirtying more stuff than we thought we would. We “need” to know
how much we will dirty so that we can check if we should fail this
transaction with ENOSPC/EDQUOT, in dmu_tx_assign(). While the
transaction is open (i.e. between dmu_tx_assign() and dmu_tx_commit() —
typically less than a millisecond), we call dbuf_dirty() on the exact
blocks that will be modified. Once this happens, the temporary
accounting in tx_space_* is unnecessary, because we know exactly what
blocks are newly dirtied; we call dnode_willuse_space() to track this
more exact accounting.
The fundamental problem causing this bug is that dmu_tx_hold_*() relies
on the current state in the DMU (e.g. dn_nlevels) to predict how much
will be dirtied by this transaction, but this state can change before we
actually perform the transaction (i.e. call dbuf_dirty()).
This bug will be fixed by removing the assertion that the tx_space_*
accounting is perfectly accurate (i.e. we never dirty more than was
predicted by dmu_tx_hold_*()). By removing the requirement that this
accounting be perfectly accurate, we can also vastly simplify it, e.g.
removing most of the logic in dmu_tx_count_*().
The new tx space accounting will be very approximate, and may be more or
less than what is actually dirtied. It will still be used to determine
if this transaction will put us over quota. Transactions that are marked
by dmu_tx_mark_netfree() will be excepted from this check. We won’t make
an attempt to determine how much space will be freed by the transaction
— this was rarely accurate enough to determine if a transaction should
be permitted when we are over quota, which is why dmu_tx_mark_netfree()
was introduced in 2014.
We also won’t attempt to give “credit” when overwriting existing blocks,
if those blocks may be freed. This allows us to remove the
do_free_accounting logic in dbuf_dirty(), and associated routines. This
logic attempted to predict what will be on disk when this txg syncs, to
know if the overwritten block will be freed (i.e. exists, and has no
snapshots).

This patch adds a command (-c) option to zpool status and zpool iostat. The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat. The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command. For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful
if the command you're running requires a /dev/sd* device.
The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper. This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root. This means that UDEV_UPATH get set correctly

When building from the head of a branch a release number is
automatically generated with `git describe` using the last tag
on that branch as the base. For this to work the last tag on the
branch needs to be predictable given the current META file.
This logic was accidentally broken when an -rcX tag was added to
the branch. Update it to search for a VERSION or VERSION-RELEASE
tag.

ZFS Test Suite Performance Regression Tests
This was pulled into OpenZFS via the compressed arc featureand was
separated out in zfsonlinux as a separate pull request from PR-4768.
It originally came in as QA-4903 in Delphix-OS from John Kennedy.
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh -r perf-regression.run
Porting Notes:
1. Added assertions in the setup script to make sure required tools
(fio, mpstat, ...) are present.
2. For the config.json generation in perf.shlib used arcstats and
other binaries instead of dtrace to query the values.
3. For the perf data collection:
- use "zpool iostat -lpvyL" instead of the io.d dtrace script
(currently not collecting zfs_read/write latency stats)
- mpstat and iostat take different arguments
- prefetch_io.sh is a placeholder that uses arcstats instead of
dtrace
4. Build machines require fio, mdadm and sysstat pakage (YMMV).
Future Work:
- Need a way to measure zfs_read and zfs_write latencies per pool.
- Need tools to takes two sets of output and display/graph the
differences
- Bring over additional regression tests from Delphix
When using real devices, specify DISKS="sdb sdc sdd" opposed to
/dev/sdb in zfs-tests.sh - otherwise errors with directory names and
disk names registering as "/dev//dev/sdb" for some tests. The same
goes for mpath: DISK="mpatha mpathad mpathb"
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh
SLICE_PREFIX is now set as "p" for a loop device (ie loop0p2) or
"" for a real device (ie sdb2), or either for multipath devices
(ie mpatha1 or mpath1p1) instead of only "p" by default. Note that
kpartx partitioning is not currently supported in this patch
(ie "partx") and may need to be disabled on Debian distributions.
Functions added for determining test directory (/dev or /dev/mapper)
as well as slice prefix are determined and exported mostly in the cfg
file of each test group directory.
Currently zpools cannot be created on whole mpath devices that have
been partitioned. In order to fix this tests have either been revised
to use a partition instead, or if there is a size constraint and the
pool needs to be created on the whole disk, partitions are then deleted
if the device is a multipath device. This functionality is added to
default_cleanup() or to individual cleanup scripts if a non-default
cleanup method is used.
The max partitions is currently set at 8 to account for all of the
tests thus far.
Patch changes are generally encompassed in "if is_linux" construct.

All users of bio->bi_rw have been replaced with compatibility wrappers.
This allows the kernel specific logic to be abstracted away, and for
each of the supported cases to be documented with the wrapper. The
updated interfaces are as follows:
* void blk_queue_set_write_cache(struct request_queue *, bool, bool)
* boolean_t bio_is_flush(struct bio *)
* boolean_t bio_is_fua(struct bio *)
* boolean_t bio_is_discard(struct bio *)
* boolean_t bio_is_secure_erase(struct bio *)
* VDEV_WRITE_FLUSH_FUA

Starting from Linux 4.7, get_acl will set acl cache pointer to temporary
sentinel value before calling i_op->get_acl. Therefore we can't compare
against ACL_NOT_CACHED and return.
Since from Linux 3.14, get_acl already check the cache for us, so we
disable this in zpl_get_acl.
Linux 4.7 also does set_cached_acl for us so we disable it in zpl_get_acl.
