e860cb0200 zvol: Remove broken blk-mq optimization
This fix removes a dubious optimization in zfs_uiomove_bvec_rq()
that saved the iterator contents of a rq_for_each_segment().  This
optimization allowed restoring the "saved state" from a previous
rq_for_each_segment() call on the same uio so that you wouldn't
need to iterate though each bvec on every zfs_uiomove_bvec_rq() call.
However, if the kernel is manipulating the requests/bios/bvecs under
the covers between zfs_uiomove_bvec_rq() calls, then it could result
in corruption from using the "saved state".  This optimization
results in an unbootable system after installing an OS on a zvol
with blk-mq enabled.

6e41aca519 Trust ARC_BUF_SHARED() more
In my understanding ARC_BUF_SHARED() and arc_buf_is_shared() should
return identical results, except the second also asserts it deeper.
The first is much cheaper though, saving few pointer dereferences.
Replace production arc_buf_is_shared() calls with ARC_BUF_SHARED(),
and call arc_buf_is_shared() in random assertions, while making it
even more strict.

On my tests this in half reduces arc_buf_destroy_impl() time, that
noticeably reduces hash_lock congestion under heavy dbuf eviction.

79f7de5752 Remove lock from dsl_pool_need_dirty_delay()
Torn reads/writes of dp_dirty_total are unlikely: on 64-bit systems
due to register size, while on 32-bit due to memory constraints.
And even if we hit some race, the code implementing the delay takes

Removal of the poll-wide lock acquisition saves ~1% of CPU time on

going to become private to FreeBSD's UMA in 15.0-CURRENT (main),
14.0-STABLE (stable/14) and 13.2-STABLE (stable/13).  Should accessing
this information become necessary again, one will have to use the new

1cc1bf4fa7 Set spa_ccw_fail_time=0 when expanding a vdev.
When a vdev is to be expanded -- either via `zpool online -e` or via
the autoexpand option -- a SPA_ASYNC_CONFIG_UPDATE request is queued
to be handled via an asynchronous worker thread (spa_async_thread).
This normally happens almost immediately; but will be delayed up to
zfs_ccw_retry_interval seconds (default 5 minutes) if an attempt to
write the zpool configuration cache failed.

When FreeBSD boots ZFS-root VM images generated using `makefs -t zfs`,
the zpoolupgrade rc.d script runs `zpool upgrade`, which modifies the
pool configuration and triggers an attempt to write to the cache file.
This attempted write fails because the filesystem is still mounted
read-only at this point in the boot process, triggering a 5-minute
cooldown before SPA_ASYNC_CONFIG_UPDATE requests will be handled by
the asynchronous worker thread.

When expanding a vdev, reset the "when did a configuration cache
write last fail" value so that the SPA_ASYNC_CONFIG_UPDATE request
will be handled promptly.  A cleaner but more intrusive option would
be to use separate SPA_ASYNC_ flags for "configuration changed" and
"try writing the configuration cache again", but with FreeBSD 14.0
coming very soon I'd prefer to leave such refactoring for a later
date.

0bcd1151f0 Fix ZED auto-replace for VDEVs using by-id paths
The change is simple -- restore the original code so that the VDEV 
path is updated when using by-id paths.  The more challenging part 
was to devise a second ZTS test, that would test auto-replace for 
'by-id' and help prevent a future regression.

With that new test, we can now do an A|B test with , and without, 
the fix to confirm that auto-replace for by-id paths works. The 
existing auto-replace test, functional/fault/auto_replace_001_pos, 
will confirm that we didn't break auto-replace for 'by-vdev' paths.

In the original functional/fault/auto_replace_001_pos test, the disk 
wipe (using dd) was not effective in removing the partitioning since 
the kernel was never informed of the wipe.

Added a call to wipefs(8) so that the kernel is informed and ZED will 
re-partition the device.
    
Added a validation step that the re-partitioning occurred by
confirming  that the GPT partition UUID changes.

6d693e20a2 Large sync writes perform worse with slog
For synchronous write workloads with large IO sizes, a pool configured
with a slog performs worse than one with an embedded zil:

sequential_writes 1m sync ios, 16 threads
  Write IOPS:              1292          438   -66.10%
  Write Bandwidth:      1323570       448910   -66.08%
  Write Latency:       12128400     36330970      3.0x

sequential_writes 1m sync ios, 32 threads
  Write IOPS:              1293          430   -66.74%
  Write Bandwidth:      1324184       441188   -66.68%
  Write Latency:       24486278     74028536      3.0x

The reason is the `zil_slog_bulk` variable. In `zil_lwb_write_open`,
if a zil block is greater than 768K, the priority of the write is
downgraded from sync to async. Increasing the value allows greater
throughput. To select a value for this PR, I ran an fio workload with
the following values for `zil_slog_bulk`:

    zil_slog_bulk    KiB/s
    1048576         422132
    2097152         478935
    4194304         533645
    8388608         623031
    12582912        827158
    16777216       1038359
    25165824       1142210
    33554432       1211472
    50331648       1292847
    67108864       1308506
    100663296      1306821
    134217728      1304998

At 64M, the results with a slog are now improved to parity with an
embedded zil:

sequential_writes 1m sync ios, 16 threads
  Write IOPS:               438         1288      2.9x
  Write Bandwidth:       448910      1319062      2.9x
  Write Latency:       36330970     12163408   -66.52%

sequential_writes 1m sync ios, 32 threads
  Write IOPS:               430         1290      3.0x
  Write Bandwidth:       441188      1321693      3.0x
  Write Latency:       74028536     24519698   -66.88%

None of the other tests in the performance suite (run with a zil or
slog) had a significant change, including the random_write_zil tests,
which use multiple datasets.

2bba9fd479 Zpool can start allocating from metaslab before TRIMs have completed
When doing a manual TRIM on a zpool, the metaslab being TRIMmed is
potentially re-enabled before all queued TRIM zios for that metaslab
have completed. Since TRIM zios have the lowest priority, it is 
possible to get into a situation where allocations occur from the 
just re-enabled metaslab and cut ahead of queued TRIMs to the same 
metaslab.  If the ranges overlap, this will cause corruption.

We were able to trigger this pretty consistently with a small single 
top-level vdev zpool (i.e. small number of metaslabs) with heavy 
parallel write activity while performing a manual TRIM against a 
somewhat 'slow' device (so TRIMs took a bit of time to complete). 
With the patch, we've not been able to recreate it since. It was on 
illumos, but inspection of the OpenZFS trim code looks like the 
relevant pieces are largely unchanged and so it appears it would be 
vulnerable to the same issue.

da93b72c91 mailmap: initial, trying to tidy up a lot of the commit history
This comes from the observation that a huge number of commit author
fields look quite strange (to my eyes), but quite often the
Signed-off-by: trailer has the correct name. For these I have updated
the name where it was obvious how to do so, however, I have not created
a mapping for the commit email to the Signed-off-by email, as whatever I
choose for email will become the prime candidate for inclusion in the
AUTHORS file, and care needs to be taken when acting without explicit
consent.

There's a small handful of commits that look like they were done on
local machines, or CI hosts, or similar, where the git authorship config
wasn't set up properly. Its obvious what this should look like, so I've
just done them.

The remainder is mapping Github noreply emails to either an
obviously-correct Signed-off-by trailer, or to a an author from another
commit. This was mostly done by hand, so there may be errors, but I
think its close. I do not understand where these come from - I know that
they're what commits made via Github web look like when there's no real
address set on the account, but I find it hard to believe that so many
of these came through the web, especially given the complexity of most
of the changes. I suspect there's some kind of merge helper tool in play
here. Regardless, the history is set now, and this tries to get it back
on track.

Obviously, all of this helps the history look tidy, but this also feeds
into the AUTHORS update script. See next commit.

9be8ddfb3c ZIL: Reduce maximum size of WR_COPIED to 7.5K
Benchmarks show that at certain write sizes range lock/unlock take
not so much time as extra memory copy.  The exact threshold is not
obvious due to other overheads, but it is definitely lower than
~63KB used before.  Make it configurable, defaulting at 7.5KB,
that is 8KB of nearest malloc() size minus itx and lr structs.

3755cde22a 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

33d7c2d165 import: require force when cachefile hostid doesn't match on-disk
Previously, if a cachefile is passed to zpool import, the cached config
is mostly offered as-is to ZFS_IOC_POOL_TRYIMPORT->spa_tryimport(), and
the results are taken as the canonical pool config and handed back to
ZFS_IOC_POOL_IMPORT.

In the course of its operation, spa_load() will inspect the pool and
build a new config from what it finds on disk. However, it then
regenerates a new config ready to import, and so rightly sets the hostid
and hostname for the local host in the config it returns.

Because of this, the "require force" checks always decide the pool is
exported and last touched by the local host, even if this is not true,
which is possible in a HA environment when MMP is not enabled. The pool
may be imported on another head, but the import checks still pass here,
so the pool ends up imported on both.

(This doesn't happen when a cachefile isn't used, because the pool
config is discovered in userspace in zpool_find_import(), and that does
find the on-disk hostid and hostname correctly).

Since the systemd zfs-import-cache.service unit uses cachefile imports,
this can lead to a system returning after a crash with a "valid"
cachefile on disk and automatically, quietly, importing a pool that has
already been taken up by a secondary head.

This commit causes the on-disk hostid and hostname to be included in the
ZPOOL_CONFIG_LOAD_INFO item in the returned config, and then changes the
"force" checks for zpool import to use them if present.

This method should give no change in behaviour for old userspace on new
kernels (they won't know to look for the new config items) and for new
userspace on old kernels (the won't find the new config items).

bcd010d3a5 Reduce number of metaslab preload taskq threads.
Before this change ZFS created threads for 50% of CPUs for each top-
level vdev.  Plus it created the same number of threads for embedded
log groups (that have only one metaslab and don't need any preload).
As result, on system with 80 CPUs and pool of 60 vdevs this resulted
in 4800 metaslab preload threads, that is absolutely insane.

This patch changes the preload threads to 50% of CPUs in one taskq
per pool, so on the mentioned system it will be only 40 threads.

Among other things this fixes zdb on the mentioned system and pool
on FreeBSD, that failed to create so many threads in one process.

3158b5d718 ARC: Drop different size headers for crypto
To reduce memory usage ZFS crypto allocated bigger by 56 bytes ARC
headers only when specific block was encrypted on disk.  It was a
nice optimization, except in some cases the code reallocated them
on fly, that invalidated header pointers from the buffers.  Since
the buffers use different locking, it created number of races, that
were originally covered (at least partially) by b_evict_lock, used
also to protection evictions.  But it has gone as part of #14340.
As result, as was found in #15293, arc_hdr_realloc_crypt() ended
up unprotected and causing use-after-free.

Instead of introducing some even more elaborate locking, this patch
just drops the difference between normal and protected headers. It
cost us additional 56 bytes per header, but with couple patches
saving 24 bytes, the net growth is only 32 bytes with total header
size of 232 bytes on FreeBSD, that IMHO is acceptable price for
simplicity.  Additional locking would also end up consuming space,
time or both.

ba7797c8db ARC: Remove b_bufcnt/b_ebufcnt from ARC headers
In most cases we do not care about exact number of buffers linked
to the header, we just need to know if it is zero, non-zero or one.
That can easily be checked just looking on b_buf pointer or in some
cases derefencing it.

b_ebufcnt is read only once, and in that case we already traverse
the list as part of arc_buf_remove(), so second traverse should not
be expensive.

This reduces L1 ARC header size by 8 bytes and full crypto header by
16 bytes, down to 176 and 232 bytes on FreeBSD respectively.

This saves 16 bytes of L1 ARC header on FreeBSD (reducing it from
200 to 184 bytes) and seems even more on Linux.

8015e2ea66 Add '-u' - nomount flag for zfs set
This commit adds '-u' flag for zfs set operation. With this flag,
mountpoint, sharenfs and sharesmb properties can be updated
without actually mounting or sharing the dataset.

Previously, if dataset was unmounted, and mountpoint property was
updated, dataset was not mounted after the update. This behavior
is changed in #15240. We mount the dataset whenever mountpoint
property is updated, regardless if it's mounted or not.

To provide the user with option to keep the dataset unmounted and
still update the mountpoint without mounting the dataset, '-u'
flag can be used.

If any of mountpoint, sharenfs or sharesmb properties are updated
with '-u' flag, the property is set to desired value but the
operation to (re/un)mount and/or (re/un)share the dataset is not
performed and dataset remains as it was before.

c53bc3837c Improve the handling of sharesmb,sharenfs properties
For sharesmb and sharenfs properties, the status of setting the
property is tied with whether we succeed to share the dataset or
not. In case sharing the dataset is not successful, this is
treated as overall failure of setting the property. In this case,
if we check the property after the failure, it is set to on.

This commit updates this behavior and the status of setting the
share properties is not returned as failure, when we fail to
share the dataset.

For sharenfs property, if access list is provided, the syntax
errors in access list/host adresses are not validated until after
setting the property during postfix phase while trying to
share the dataset. This is not correct, since the property has
already been set when we reach there.

Syntax errors in access list/host addresses are validated while
validating the property list, before setting the property and
failure is returned to user in this case when there are errors
in access list.

e9dc31c74e Update the behavior of mountpoint property
There are some inconsistencies in the handling of mountpoint
property. This commit updates the behavior and makes it
consistent.

If mountpoint property is set when dataset is unmounted, this
would update the mountpoint property. The mountpoint could be
valid or invalid in this case. Setting the mountpoint property
would result in success in this case. Dataset would still be
unmounted here.

On the other hand, if dataset is mounted and mountpoint
property is updated to something invalid where mount cannot be
successful, for example, setting the mountpoint inside a readonly
directory. This would unmount the dataset, set the mountpoint
property to requested value and tries to mount the dataset. The
mount operation returns error and this error is treated as
overall failure of setting the property while the property is
actually set.

To make the behavior consistent in case dataset is mounted or
unmounted, we should try to mount the dataset whenever mountpoint
property is updated. This would result in mounting the datasets
if canmount property is set to on, regardless if the dataset was
previously unmounted.

The failure in mount operation while setting the mountpoint
property should not be treated as failure, since the property is
actually set now to user requested value.

db5c3b4c76 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.
