Brian Behlendorf ff1acbac30 ZTS: speed up rsend tests
With some minor tweaks several of rsend tests can be sped up
considerably without significantly reducing test coverage.

* send-c_verify_ratio:  ~120s -> ~60s
* send_realloc_*_files: ~330s -> ~65s

For the send_realloc* tests this also has the advantage of removing
(most of) the linux/freebsd conditional logic.  Note that for this
test more passes, and thus more incremental send/recvs, are preferable
to a larger number of files.

Total run time of the rsend test group was reduced from roughly 20 to
11 minutes in an environment similar to what's used by the CI.

Brian Behlendorf 7b5d783a46 ZTS: rsend_007_pos failures
The rsend_007_pos test reliably fails on Linux in the cleanup
function.  This is caused by an unmount error when attempting to
recursively destroy the newly received datasets.  Invoking `df`
prior to the `zfs destroy` interestingly avoids the unmont error.

Why this should matter is unclear and should be investigated.
However, this minor tweak may allow us to remove the ZTS rsend
exceptions.  The subsequent rsend_010_pos and rsend_011_pos
failures were a result of this initial failure.  The other
"maybe" failures I was unable to reproduce and have not been
recently observed in the master branch.

Fix zvol_open() lock inversion
When restructuring the zvol_open() logic for the Linux 5.13 kernel
a lock inversion was accidentally introduced.  In the updated code
the spa_namespace_lock is now taken before the zv_suspend_lock
allowing the following scenario to occur:

    down_read <=== waiting for zv_suspend_lock
    zvol_open <=== holds spa_namespace_lock
    __blkdev_get
    blkdev_get_by_dev
    blkdev_open
    ...

     mutex_lock <== waiting for spa_namespace_lock
     spa_open_common
     spa_open
     dsl_pool_hold
     dmu_objset_hold_flags
     dmu_objset_hold
     dsl_prop_get
     dsl_prop_get_integer
     zvol_create_minor
     dmu_recv_end
     zfs_ioc_recv_impl <=== holds zv_suspend_lock via zvol_suspend()
     zfs_ioc_recv
     ...

This commit resolves the issue by moving the acquisition of the
spa_namespace_lock back to after the zv_suspend_lock which restores
the original ordering.

Additionally, as part of this change the error exit paths were
simplified where possible.

zcommon: pre-iterate over sysfs instead of statting every feature
If sufficient memory (<2K, realistically) is available, libzfs_init()
can be significantly shorted by iterating over the correct sysfs
directory before registrations, we can turn 168 stats into 15/18
syscalls (3 opens (6 if built in), 3 fstats, 6 getdentses, and 3
closes), a tenfoldish reduction; this is probably a bit faster, too.

The list is always optional, and registration functions (and one-off
users) can simply pass NULL, which will fall back to the previous
mechanism

Also, don't allocate in zfs_mod_supported_impl, and use use access()
instead of stat(), since existence is really what we care about

Also, fix pre-prop-checking compat in fallback for built-in ZFS

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.

contrib/bash_completion.d: fix error spew from __zfs_match_snapshot()
Given:
  /sbin/zfs list filling/a-zvol<TAB> -o space,refratio
The rest of the cmdline gets vored by:
  /sbin/zfs list filling/a-zvolcannot open 'filling/a-zvol':
  operation not applicable to datasets of this type

With -x (fragment):
  + COMPREPLY=($(compgen -W "$(__zfs_match_snapshot)" -- "$cur"))
  +++ __zfs_match_snapshot
  +++ local base_dataset=filling/dziadtop-nowe-duchy
  +++ [[ filling/dziadtop-nowe-duchy != filling/dziadtop-nowe-duchy ]]
  +++ [[ filling/dziadtop-nowe-duchy != '' ]]
  +++ __zfs_list_datasets filling/dziadtop-nowe-duchy

  +++ echo filling/dziadtop-nowe-duchy
  +++ echo filling/dziadtop-nowe-duchy@

This properly completes with:

  filling/a-zvol   filling/a-zvol@
  $ /sbin/zfs list filling/a-zvol<cursor> -o space,refratio

Coleman Kane a78f19d3ec Linux 5.16: Resolve ZSTD_isError symbol collision in Linux kernel
Newer zstd code introduced in the main kernel tree now creates a symbol
collision with ZSTD_isError in our ZSTD code. This change relabels our
implementation with a ZFS-specific symbol name, and undoes some
macro-based micro-optimizations that conflict with the attempt to rename
our internal-use version.

Coleman Kane 1e767532f2 Linux 5.16: The blk-cgroup.h header is where struct blkcg_gq is defined
The definition of struct blkcg_gq was moved into blk-cgroup.h, which is
a header that's been in Linux since 2015. This is used by
vdev_blkg_tryget() in module/os/linux/zfs/vdev_disk.c. Since the kernel
for CentOS 7 and similar-generation releases doesn't have this header,
its inclusion is guarded by a configure test.

Coleman Kane d08b99aca0 Linux 5.16: bio_set_dev is no longer a helper macro
This change adds a confiugre check to determine if bio_set_dev is a
helper macro or not. If not, then the attempt to override its internal
call to bio_associate_blkg(), with a macro definition to our own
version, is no longer possible, as the compiler won't use it when
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.

Coleman Kane f6e22561d2 Linux 5.16: type member of iov_iter renamed iter_type
The iov_iter->type member was renamed iov_iter->iter_type. However,
while looking into this, realized that in 2018 a iov_iter_type(*iov)
accessor function was introduced. So if that is present, use it,
otherwise fall back to trying the existing behavior of directly
accessing type from iov_iter.
