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.

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

54b1b1d893 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).

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.

75a2eb7fac 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.

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.

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.

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.

Invoke zdb by guid to avoid import errors
The problem that was occurring is basically that a device was removed 
by ztest and replaced with another device. It was then reguided. The 
import then failed because there were two possible imports with the 
same name; one with the new guid, and one with the old. This can 
happen because the label writes from the device removal/replacement 
can be subject to ztest's error injection. 

The other ways to fix this would be to change the error injection to 
not trigger on removals (which may not be technically feasible), or 
to change the import code to not report configurations that are so 
short on devices (which would potentially have unpleasant end-user 
effects when trying to recover from data losses/device configuration 
issues).

In Linux commit 13bc24457850583a2e7203ded05b7209ab4bc5ef, direct access

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.

tests/block_cloning: try harder to stay on same txg in fallback test
We've observed this test failing intermittently. When it does, the
"same block" check shows that both files have the same content, that is,
the file was cloned.

The only way this could have happened is if the open txg moved between
the dd and clonefile calls. That's possible because although we set
zfs_txg_timeout to be large, that only affects the wait time in the sync
thread at the start of a new txg; it doesn't change anything if its
currently waiting or working.

So here we just force the txgs to move immediately before, which should
get both operations onto the same txg as intented.

status: report pool suspension state under failmode=continue
When failmode=continue is set and the pool suspends, both 'zpool status'
and the 'zfs/pool/state' kstat ignore it and report the normal vdev tree
state. There's no clear indicator that the pool is suspended. This is
unlike suspend in failmode=wait, or suspend due to MMP check failure,
which both report "SUSPENDED" explicitly.

This commit changes it so SUSPENDED is reported for failmode=continue
the same as for other modes.

Rationale:

The historical behaviour of failmode=continue is roughly, "press on as
though all is well". To this end, the fact that the pool had suspended
was not shown, to maintain the façade that all is well.

Its unclear why hiding this information was considered appropriate. One
possibility is that it was expected that a true pool fault would always
be reported as DEGRADED or FAULTED, and that the pool could not suspend
without these happening.

That is not necessarily true, as vdev health and suspend state are only
loosely connected, such that a pool in (apparent) good health can be
suspended for good reasons, and of course a degraded pool does not lead
to suspension. Even if that expectation were true, there's still a
difference in urgency - a degraded pool may not need to be attended to
for hours, while a suspended pool is most often unusable until an
operator intervenes.

An operator that has set failmode=continue has presumably done so
because their workload is one that can continue to operate in a useful
way when the pool suspends. In this case the operator still needs a
clear indicator that there is a problem that needs attending to.

Fix occasional rsend test crashes
We have occasional crashes in the rsend tests. Debugging revealed 
that this is because the send_worker thread is getting EINTR from 
splice(). This happens when a non-fatal signal is received during 
the syscall. We should retry the syscall, rather than exiting failure.
Tweak the loop to only break if the splice is finished or we receive 
a non-EINTR error.

ZIL: Fix potential race on flush deferring.
zil_lwb_set_zio_dependency() can not set write ZIO dependency on
previous LWB's write ZIO if one is already in done handler and set
state to LWB_STATE_WRITE_DONE.  So theoretically done handler of
next LWB's write ZIO may run before done handler of previous LWB
write ZIO completes.  In such case we can not defer flushes, since
the flush issue process is not locked.

This may fix some reported assertions of lwb_vdev_tree not being
empty inside zil_free_lwb().

c63aabaf1c 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.

bbac1d2977 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.

cmd: add 'help' subcommand to zpool and zfs
'program help subcommand' is a reasonably common pattern for
multifunction command-line programs. This commit adds support for that
style to the zpool and zfs commands.

When run as 'zpool help [<topic>]' or 'zfs help [<topic>]', executes the
'man' program on the PATH with the most likely manpage name for the
requested topic: "zpool-<topic>" or "zfs-<topic>" for subcommands, or
"zpool<topic>" or "zfs<topic>" for the "concepts" and "props" topics.
If no topic is supplied, uses the top "zpool" or "zfs" pages.

Fix l2arc_apply_transforms ztest crash
In #13375 we modified the allocation size of the buffer that we use 
to apply l2arc transforms to be the size of the arc hdr we're using, 
rather than the allocation size that will be in place on the disk, 
because sometimes the hdr size is larger. Unfortunately, sometimes 
the allocation size is larger, which means that we overflow the buffer 
in that case. This change modifies the allocation to be the max of 
the two values

spa_upgrade_errlog() does not update the MOS directory when the
