I've found that QEMU/KVM guest memory accounted as shared also
included into NR_FILE_PAGES. But it is actually a non-evictable
anonymous memory. Using it as a base for zfs_arc_pc_percent
parameter makes ARC to ignore shrinker requests while page cache
does not really have anything to evict, ending up in OOM killer
killing the QEMU process.
Instead use of NR_ACTIVE_FILE + NR_INACTIVE_FILE should represent
the part of a page cache that is actually evictable, which should
be safer to use as a reference for ARC scaling.

Allow installing a custom kernel version from the Fedora experimental
kernel repos onto the github runners. This is useful for testing if
ZFS works against a newer kernel.
Fedora has a number of repos with experimental kernel packages. This
PR allows installs from kernels in these repos:
@kernel-vanilla/stable
@kernel-vanilla/mainline
(https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories)
You will need to manually kick of a github runner to test with a custom
kernel version. To do that, go to the github actions tab under
'zfs-qemu' and click the drop-down for 'run workflow'. In there you
will see a text box to specify the version (like '6.14'). The scripts
will do their best to match the version to the newest matching version
that the repos support (since they're may be multiple nightly versions
of, say, '6.14'). A full list of kernel versions can be seen in the
dependency stage output if you kick off a manual run.

Once we've selected a best ident for the AUTHORS file, it makes sense to
set up a corresponding mailmap entry for any other ident for that
committer, to ensure the git history also reflects this into the future.
So, here we output potential mailmap updates for a human to consider.
For the moment, this needs to be done by a human, because update_authors
uses git to get the author names, and thus is reliant on the mailmap
contents to generate its output, so having it update mailmap directly
would introduce a circular dependency that I'm not totally sure about.
It's definitely better than having to go back through the history and
check each commit by hand though.

I've increasingly found that commits from new contributors have the
author set in the "Github noreply" obfuscated style. If they do have a
better canonical choice, it's usually in the Signed-off-by: trailer in
the commit message.
I had avoided using these in the first version of this program because
they aren't always present, aren't always correct, and some commits have
multiple signoffs. It seems however that requiring either the name or
the email address to match the commit author sufficiently narrows the
scope to be useful for the "Github noreply" situation, which is really
the main sticking point. And of course, if it gets it wrong, overriding
in .mailmap or AUTHORS is always an option.

The old code would compare all the test group names to work out some
sort of common path, but it didn't appear to work consistently,
sometimes placing output in a top-level dir, other times in one or more
subdirs. (I confess, I do not quite understand what it's supposed to
do).
This is a very simple rework that simply looks at all the test group
paths, removes common leading components, and uses the remainder as the
output directory. This should work because groups paths are unique, and
means we get a output dir tree of roughly the same shape as the test
groups in the runfiles and the test source dirs themselves.

Instead of a boolean, the return is now an error code, which the caller

Closes#17235
(cherry picked from commit aa46cc9812)
### Background
Various admin operations will be invoked by some userspace task, but the
work will be done on a separate kernel thread at a later time. Snapshots
are an example, which are triggered through zfs_ioc_snapshot() ->
dsl_dataset_snapshot(), but the actual work is from a task dispatched to
dp_sync_taskq.
Many such tasks end up in dsl_enforce_ds_ss_limits(), where various
limits and permissions are enforced. Among other things, it is necessary
to ensure that the invoking task (that is, the user) has permission to
do things. We can't simply check if the running task has permission; it
is a privileged kernel thread, which can do anything.
However, in the general case it's not safe to simply query the task for
its permissions at the check time, as the task may not exist any more,
or its permissions may have changed since it was first invoked. So
instead, we capture the permissions by saving CRED() in the user task,
and then using it for the check through the secpolicy_* functions.
### Current implementation
The current code calls CRED() to get the credential, which gets a
pointer to the cred_t inside the current task and passes it to the
worker task. However, it doesn't take a reference to the cred_t, and so
expects that it won't change, and that the task continues to exist. In
practice that is always the case, because we don't let the calling task
return from the kernel until the work is done.
For Linux, we also take a reference to the current task, because the
Linux credential APIs for the most part do not check an arbitrary
credential, but rather, query what a task can do. See
secpolicy_zfs_proc(). Again, we don't take a reference on the task, just
a pointer to it.
### Changes
We change to calling crhold() on the task credential, and crfree() when
we're done with it. This ensures it stays alive and unchanged for the
duration of the call.
On the Linux side, we change the main policy checking function
priv_policy_ns() to use override_creds()/revert_creds() if necessary to
make the provided credential active in the current task, allowing the
standard task-permission APIs to do the needed check. Since the task
pointer is no longer required, this lets us entirely remove
secpolicy_zfs_proc() and the need to carry a task pointer around as
well.

Previous implementation of zap_leaf_array_free() put chunks on the
free list in reverse order. Also zap_leaf_transfer_entry() and
zap_entry_remove() were freeing name and value arrays in reverse
order. Together this created a mess in the free list, making
following allocations much more fragmented than necessary.
This patch re-implements zap_leaf_array_free() to keep existing
chunks order, and implements non-destructive zap_leaf_array_copy()
to be used in zap_leaf_transfer_entry() to allow properly ordered
freeing name and value arrays there and in zap_entry_remove().
With this change test of some writes and deletes shows percent of
non-contiguous chunks in DDT reducing from 61% and 47% to 0% and
17% for arrays and frees respectively. Sure some explicit sorting
could do even better, especially for ZAPs with variable-size arrays,

IVs != 96 bits get hashed with GHASH to bring them to 96 bits. Any call
to GHASH will mix the ghash state in gcm_ghash. This is expected to be
zero at first use in an encrypt or decrypt operation, so it needs to be
zeroed after using GHASH in setup.
gcm_init() does this, but gcm_avx_init() zeroed it before setup, not
after, resulting in incorrect encrypt/decrypt results when using AVX GCM
with an IV != 96 bits.
OpenZFS _always_ uses a 96 bit IV (ZIO_DATA_IV_LEN) so this will never
have been hit in any real-world use, which is extremely fortunate, as we
would have incorrectly-encrypted data on-disk. Still, as long as we have
