ZFS always waits for the write completion before flushing the cache.
That is why it does not require explicit ordering fences around it,
which are pretty difficult to implement for NVMe, since one has no
internal concept of strict request ordering.
This was already removed from FreeBSD once, but got resurrected
by mistake during OpenZFS merge.

Previously, xattr_004_pos would create files with xattrs on both
tmpfs and ext2, and then copy them to zfs to verify that their
xattrs were preserved. However tmpfs doesn't support xattrs.
This was never noticed until Fedora 33. In Fedora 32 and older,
/tmp was on the root partition (like ext4), whereas on Fedora 33
/tmp is actually tmpfs. That caused this test to fail on Fedora 33.
This fix updates the test to only create the file on ext2, not tmpfs.

The port removed provisions for zfs_znode_move but the cleanup missed
this bit. To quote the original:
[snip]
list_insert_tail(&zfsvfs->z_all_znodes, zp);
membar_producer();
/*
* Everything else must be valid before assigning z_zfsvfs makes the
* znode eligible for zfs_znode_move().
*/
zp->z_zfsvfs = zfsvfs;
[/snip]
In the current code it is immediately followed by unlock which issues
the same fence, thus plays no role in correctness.

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)

The zstd code assumes that if you are on aarch64, you have NEON
instructions. This is not necessarily true. In a boot loader, where
you might not have the VFP properly initialized, these instructions
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.
