  NFSv4/flexfiles: Fix layout merge mirror check. (2025-09-08 14:37:55 -0400)

Thanks,
  Trond

----------------------------------------------------------------
NFS client bugfixes for Linux 6.17

Stable patches:
 - Revert "SUNRPC: Don't allow waiting for exiting tasks" as it is
   breaking ltp tests.

Bugfixes:
 - Another set of fixes to the tracking of NFSv4 server capabilities
   when crossing filesystem boundaries.
 - Localio fix to restore credentials and prevent triggering a BUG_ON().
 - Fix to prevent flapping of the localio on/off trigger.
 - Protections against 'eof page pollution' as demonstrated in xfstests
   generic/363.
 - Series of patches to ensure correct ordering of O_DIRECT i/o and
   truncate, fallocate and copy functions.
 - Fix a NULL pointer check in flexfiles reads that regresses 6.17.
 - Correct a typo that breaks flexfiles layout segment processing.
