[clang] Allow clang only write module/pch when output is different (#198881)
Add an parameter to the output file creation function in clang to allow
it to configure output backend to only write output if the file is
different from the file on the disk. This is useful in a legacy build
system where the incremental build state is tracked by timestamp. For
example, producing the same clang module in the build will not update
the timestamp, thus downstream jobs do not need to be re-run.
The default value is not change so NFI is expected. This is only to
allow clients need such behavior to enable when needed.

p9fs.4: MLINK to virtio_p9fs.4
Technically, virtio_p9fs is an emulated device that masquerades
as a p9fs mount, but it does not make sense to have two separate manual
pages.

iSCSI ALUA: regression test for failover LUN-replace stall
Add an extended test that builds 2 targets (25 + 10 LUNs), opens an
iSCSI session to the standby on the 25-LUN target so the kernel has
tgt_devs to clean up during become_active, then triggers an ungraceful
failover via poweroff_vm. Asserts:
- /var/log/failover.log on the new master does not contain
'Failed to restart service "iscsitarget" after 15 seconds',
which would indicate the LUN-replace loop stalled.
- /sys/kernel/scst_tgt/async_lun_replace reads 0 after failover,
confirming reset_active released the parked cleanup work.
- All LUNs are reachable on the new master.
A function-scoped fixture handles recovery (start_vm, wait_for_backup,
wait_for_settle) so the cluster is restored to a clean two-node state
even if an assertion above failed.
Uses the dataset() asset helper rather than zvol() for lower
per-extent overhead at this scale.
Release parked async LUN-replace cleanup after DLM peer eviction
scst.async_lun_replace=1 now also tells the kernel to park the deferred
cleanup of old tgt_devs from each LUN replace until the flag is cleared.
This avoids stalling become_active on scst_dlm_lock_wait inside
scst_clear_reservation while the dead peer is still a DLM lockspace
member.
Add iscsi.scst.disable_async_lun_replace and call it from the end of
iscsi.alua.reset_active, after dlm.reset_active (which evicts the peer)
completes.
CI: Build custom branch from zfs-qemu-packages
The zfs-qemu-packages workflow allows us to easily build RPMs for the
current branch. However, there can be cases where we want to use the
current CI environment to build older releases. This can happen when
the VM or runner environment changes, and the older CI doesn't have
the updates needed to run with it anymore.
This commit adds in a text box to specify a specific branch/tag to build
using the current CI environment.

Optimization on predecessor count checks for FunctionPropertiesAnalysis (#198940)
It used to need to get the whole bb predecessor count and then check
with the size of it. That needed to go through the whole list only to
check against 1, 2 or 3. By using its already existing basic block
predecessor count function, these attributes can be counted much faster.
Now it doesn't need to go through the whole list. The moment it gets to
the 3rd element, no matter how many predecessors there might be, we have
our answer for the metrics
