FreeBSD: Provide correct file generation number
va_seq was actually a thin veil over va_gen, so z_gen is a more
appropriate value than z_seq to populate the field with.

Drop the unnecessary compat obfuscation and provide the correct
file generation number.

zfs list: Allow more fields in ZFS_ITER_SIMPLE mode
If the fields to be listed and sorted by are constrained
to those populated by dsl_dataset_fast_stat(), then
zfs list is much faster, as it does not need to open each
objset and reads its properties.

A previous optimization by Pawel Dawidek
(0cee24064a) took advantage
of this to make listing snapshot names sorted only by name
much faster.

However, it was limited to `-o name -s name`, this work
extends this optimization to work with:
  - name
  - guid
  - createtxg
  - numclones
  - inconsistent
  - redacted
  - origin
and could be further extended to any other properties
supported by dsl_dataset_fast_stat() or similar, that do
not require extra locking or reading from disk.

Mark Johnston cdf74673bc zfs: Fix a deadlock between page busy and the teardown lock
When rolling back a dataset, ZFS has to purge file data resident in the
system page cache.  To do this, it loops over all vnodes for the
mountpoint and calls vn_pages_remove() to purge pages associated with
the vnode's VM object.  Each page is thus exclusively busied while the
dataset's teardown write lock is held.

When handling a page fault on a mapped ZFS file, FreeBSD's page fault
handler busies newly allocated pages and then uses VOP_GETPAGES to fill
them.  The ZFS getpages VOP acquires the teardown read lock with vnode
pages already busied.  This represents a lock order reversal which can
lead to deadlock.

To break the deadlock, observe that zfs_rezget() need only purge those
pages marked valid, and that pages busied by the page fault handler are,
by definition, invalid.  Furthermore, ZFS pages always transition from
invalid to valid with the teardown lock held, and ZFS never creates
partially valid pages.  Thus, zfs_rezget() can use the new
vn_pages_remove_valid() to skip over pages busied by the fault handler.

This change adds a confiugre check to determine if bio_set_dev is a

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.

Code cleanups
- Allocate ve_search on the stack, so we avoid allocating memory for
  every I/O even if the VDEV cache is disabled.
- Reduce lock scope.
- Avoid locking in vdev_cache_read() when the VDEV cache is disabled.
- Sort file names properly.
- Correct comment.

on special vdevs too. So let's make -MM do something useful.

Pass `--enable=all` to shellcheck within contrib/
- Remove `SHELLCHECK_IGNORE` in favor of inline suppressions
  and more general `SHELLCHECK_OPTS`.

- Exclude `SC2250` (turned on by `--enable=all`) globally

- Pass `--enable=all` to shellcheck for scripts in contrib/: it's
  very important to catch errors early in areas that are not easily
  testable.

etc/systemd/zfs-mount-generator: serialise, handle keylocation=http[s]://
* etc/systemd/zfs-mount-generator: serialise

The wins for a relatively normal workload are rather slim:
	real	0.02119s/0.00985s=2.15029x
	user	0.02130s/0.00346s=6.15560x
	sys	0.03858s/0.00643s=6.00062x

	wall-total	0.014518s/0.005925s=2.45009x
	wall-init	0.014518s/0.002457s=5.90684x
	wall-real	0.014518s/0.003467s=4.18668x

But this is a big win on machines with a lot of datasets and expensive
forks.

For example, the gain on a VM on my work laptop with 900+ legacy-mount
Docker datasets, the original gains from the C rewrite were
only five-fold:
	real    0.516s/0.102s=5.05882x
	user    0.237s/0.143s=1.65734x
	sys     0.287s/0.100s=2.87x

And this serial variant gains this back there as well:
	real    0.102s/0.008s=12.75x
	user    0.143s/0.007s=20.42857
	sys     0.100s/0.001s=100x

	wall-total	0.09717s/0.00319s=30.40255x
	wall-init	0.00203s/0.00200s=1.015941x
	wall-real	0.09513s/0.00118s=80.02043x

For a total of
	real    0.516s/0.008s=64.5x
	user    0.237s/0.007s=33.85714x
	sys     0.287s/0.001s=287x

Vdev Properties Feature
Add properties, similar to pool properties, to each vdev.
This makes use of the existing per-vdev ZAP that was added as
part of device evacuation/removal.

A large number of read-only properties are exposed,
many of the members of struct vdev_t, that provide useful
statistics.

Adds support for read-only "removing" vdev property.
Adds the "allocating" property that defaults to "on" and
can be set to "off" to prevent future allocations from that
top-level vdev.

Supports user-defined vdev properties.
Includes support for properties.vdev in SYSFS.

for the presence of this header, and include it so that the code using
xgetbv & xsetbv will compile again.

Coleman Kane c0fb44c506 Linux 5.16: wait_on_page_bit() no longer available to modules
Instead, linux/pagemap.h offers a number of folio-specific functions to
be called instead. In this case, module/os/linux/zfs/zfs_vnops_os.c
wants to call wait_on_page_bit(pp, PG_writeback). This gets replaced
with folio_wait_bit(folio_page(pp), PG_writeback). This change modifies
the code to conditionally compile that if configure identifies th
presence of the folio_wait_bit() function.

Fix several bugs in the FreeBSD rename VOP implementation
- To avoid a use-after-free, zfsvfs->z_log needs to be loaded after the
  teardown lock is acquired with ZFS_ENTER().
- Avoid leaking vnode locks in zfs_rename_relock() and zfs_rename_()
  when the ZFS_ENTER() macros forces an early return.

Refactor the rename implementation so that ZFS_ENTER() can be used
safely.  As a bonus, this lets us use the ZFS_VERIFY_ZP() macro instead
of open-coding its implementation.
