of zfs/zpool subcommands instead of current "pretty-printed" ones as
makewhatis utilities (or some implementations of it, namely the one
from mandoc suite used in FreeBSD) look not only at the document title

The current l2_misses accounting behavior treats all reads to pools
without a configured l2arc as an l2arc miss, IFF there is at least
one other pool on the system which does have an l2arc configured.
This makes it extremely hard to tune for an improved l2arc hit/miss
ratio because this ratio will be modulated by reads from pools which
do not (and should not) have l2arc devices; its upper limit will
depend on the ratio of reads from l2arc'd pools and non-l2arc'd pools.
This PR prevents ARC reads affecting l2arc stats (n.b. l2_misses is
the only relevant one) where the target spa doesn't have an l2arc.
Includes new test - l2arc_l2miss_pos.ksh

The removal of a vdev in the normal class would fail if there was a

the normal class.
Moved the initialization of spa_min_ashift / spa_max_ashift from
vdev_open so that it occurs after the vdev allocation bias was
initialized (i.e. after vdev_load).
Caveat -- In order to remove a special/dedup vdev it must have the
same ashift as the normal pool vdevs. This could perhaps be lifted
in the future (i.e. for the case where there is ample space in any
surviving special class vdevs)

Currently streams are only freed when:

go to zero.
- They are more than 2s old and a new I/O request comes in on
the same zfetch.
This means that we will leak unreferenced streams when their zfetch
structure is freed.
This change checks the reference count on a stream at zfetch free
time. If it is zero we free it immediately. If it has remaining
references we allow the prefetch callback to free it at I/O
completion time.

may not be available. It's also an error to include arm_neon.h when
the NEON insturctions aren't enabled. Change the guards for using the
NEON instructions from __aarch64__ to __ARM_NEON which is the standard
symbol for knowing if they are available.
__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.

consider what happens if someone writes a lot of files and stops use of
