Add L2ARC arcstats for MFU/MRU buffers and buffer content type
Currently the ARC state (MFU/MRU) of cached L2ARC buffer and their
content type is unknown. Knowing this information may prove beneficial
in adjusting the L2ARC caching policy.

This commit adds L2ARC arcstats that display the aligned size
(in bytes) of L2ARC buffers according to their content type
(data/metadata) and according to their ARC state (MRU/MFU or
prefetch). It also expands the existing evict_l2_eligible arcstat to
differentiate between MFU and MRU buffers.

L2ARC caches buffers from the MRU and MFU lists of ARC. Upon caching a
buffer, its ARC state (MRU/MFU) is stored in the L2 header
(b_arcs_state). The l2_m{f,r}u_asize arcstats reflect the aligned size
(in bytes) of L2ARC buffers according to their ARC state (based on
b_arcs_state). We also account for the case where an L2ARC and ARC
cached MRU or MRU_ghost buffer transitions to MFU. The l2_prefetch_asize
reflects the alinged size (in bytes) of L2ARC buffers that were cached
while they had the prefetch flag set in ARC. This is dynamically updated
as the prefetch flag of L2ARC buffers changes.

When buffers are evicted from ARC, if they are determined to be L2ARC
eligible then their logical size is recorded in
evict_l2_eligible_m{r,f}u arcstats according to their ARC state upon
eviction.

Persistent L2ARC:
When committing an L2ARC buffer to a log block (L2ARC metadata) its
b_arcs_state and prefetch flag is also stored. If the buffer changes
its arcstate or prefetch flag this is reflected in the above arcstats.
However, the L2ARC metadata cannot currently be updated to reflect this
change.
Example: L2ARC caches an MRU buffer. L2ARC metadata and arcstats count
this as an MRU buffer. The buffer transitions to MFU. The arcstats are
updated to reflect this. Upon pool re-import or on/offlining the L2ARC
device the arcstats are cleared and the buffer will now be counted as an
MRU buffer, as the L2ARC metadata were not updated.

Bug fix:
- If l2arc_noprefetch is set, arc_read_done clears the L2CACHE flag of
  an ARC buffer. However, prefetches may be issued in a way that
  arc_read_done() is bypassed. Instead, move the related code in
  l2arc_write_eligible() to account for those cases too.

Also add a test and update manpages for l2arc_mfuonly module parameter,
and update the manpages and code comments for l2arc_noprefetch.
Move persist_l2arc tests to l2arc.

config/zfs-build.m4: never define _initramfs in RPM_DEFINE_UTIL
The zfs-initramfs package has never worked as no RPM-based distribution
uses initramfs-tools, which is listed as a dependency of zfs-initramfs.

This would not ordinarily be a problem, as it is only enabled when
/usr/share/initramfs-tools is present, which should not normally be the
case on RPM-based distributions. However, other packages may install
unused files there even if initramfs-tools is not used, so remove this
auto-detection for the rpm-utils target.

This does not fully remove the logic for the zfs-initramfs package. This
splits it out into a separate rpm-utils-initramfs target so that the
Debian builds can still use it.

Initialize mmp_last_write when the mmp thread starts
A great deal of time may go by between when mmp_init() is called and
the MMP thread starts, particularly if there are bad devices, because
there is I/O checking configs etc.  If this time is too long,

    (gethrtime() - mmp_last_write) > mmp_fail_ns

at the time the MMP thread starts.  If MMP is configured to suspend
the pool, the pool will be suspended immediately.

This can be seen in issue #10838

The value of mmp_last_write doesn't matter before the mmp thread
starts.  To give the MMP thread time to issue and land MMP writes,
initialize mmp_last_write when the MMP thread starts.

Avoid posting duplicate zpool events
Duplicate io and checksum ereport events can misrepresent that 
things are worse than they seem. Ideally the zpool events and the 
corresponding vdev stat error counts in a zpool status should be 
for unique errors -- not the same error being counted over and over. 
This can be demonstrated in a simple example. With a single bad 
block in a datafile and just 5 reads of the file we end up with a 
degraded vdev, even though there is only one unique error in the pool.

The proposed solution to the above issue, is to eliminate duplicates 
when posting events and when updating vdev error stats. We now save 
recent error events of interest when posting events so that we can 
easily check for duplicates when posting an error.

nowait synctask must succeed
If a `zfs_space_check_t` other than `ZFS_SPACE_CHECK_NONE` is used with
`dsl_sync_task_nowait()`, the sync task may fail due to ENOSPC.
However, there is no way to notice or communicate this failure, so it's

almost all callers use `ZFS_SPACE_CHECK_NONE`.

This commit removes the `zfs_space_check_t` argument from

Add 'zfs rename -u' to rename without remounting
Allow to rename file systems without remounting if it is possible.
It is possible for file systems with 'mountpoint' property set to
'legacy' or 'none' - we don't have to change mount directory for them.
Currently such file systems are unmounted on rename and not even
mounted back.

This introduces layering violation, as we need to update
'f_mntfromname' field in statfs structure related to mountpoint (for
the dataset we are renaming and all its children).

In my opinion it is worth it, as it allow to update FreeBSD in even
cleaner way - in ZFS-only configuration root file system is ZFS file
system with 'mountpoint' property set to 'legacy'. If root dataset is
named system/rootfs, we can snapshot it (system/rootfs@upgrade), clone
it (system/oldrootfs), update FreeBSD and if it doesn't boot we can
boot back from system/oldrootfs and rename it back to system/rootfs
while it is mounted as /. Before it was not possible, because
unmounting / was not possible.

FreeBSD: Fix spurious failure in zvol_geom_open
In zvol_geom_open on first open we need to guarantee
that the namespace lock is held to avoid spurious
failures in zvol_first_open.

FreeBSD: add support for KSTAT_TYPE_RAW
A few kstats use KSTAT_TYPE_RAW to provide a string generated on
demand.  Implementing these as sysctls was punted until now.

Linux 5.9 compat: NR_SLAB_RECLAIMABLE
Commit dcdc12e added compatibility code to treat NR_SLAB_RECLAIMABLE_B
as if it were the same as NR_SLAB_RECLAIMABLE.  However, the new value
is in bytes while the old value was in pages which means they are not
interchangeable.

The only place the reclaimable slab size is used is as a component of
the calculation done by arc_free_memory().  This function returns the
amount of memory the ARC considers to be free or reclaimable at little
cost.  Rather than switch to a new interface to get this value it has
been removed it from the calculation.  It is normally a minor component
compared to the number of inactive or free pages, and removing it
aligns the behavior with the FreeBSD version of arc_free_memory().

Richard Laager 62663fb7ec Fix another dependency loop
zfs-load-key-DATASET.service was gaining an
After=systemd-journald.socket due to its stdout/stderr going to the
journal (which is the default).  systemd-journald.socket has an After
(via RequiresMountsFor=/run/systemd/journal) on -.mount.  If the root
filesystem is encrypted, -.mount gets an After
zfs-load-key-DATASET.service.

By setting stdout and stderr to null on the key load services, we avoid
this loop.

Richard Laager ec41cafee1 Fix a dependency loop
When generating units with zfs-mount-generator, if the pool is already
imported, zfs-import.target is not needed.  This avoids a dependency
loop on root-on-ZFS systems:

config/zfs-build.m4: add --with-vendor flag
This will allow an override of auto-detection of distribution, which
is based on checking presence of /etc/*-release files.

Build systems makes a lot of file location assumptions based on
detected distribution.

Some distributions (like gentoo) may prefer explicitly
setting --with-vendor=gentoo to avoid auto-detection.

Since auto-detection checks all files in order, current script may
misdetect even on gentoo system if /etc/redhat-release file is present

Default behavior is unchanged and default is --with-vendor=check

module/zstd: pass -U__BMI__
If kernel is compiled with -march=znver1 or -march=znver2 zstd module 
compilation will fail due to SSE register return with SSE disabled.
What's interesting, is that -march=skylake also implies -mbmi which 
defines __BMI__ but compilation succeeds.  It is probably due to 
different BMI implementations on AMD and INTEL processors and the 
way compiler uses instructions.
