  NFSD: Add a Kconfig setting to enable delegated timestamps (2025-03-14 10:49:47 -0400)

----------------------------------------------------------------
NFSD 6.15 Release Notes

Neil Brown contributed more scalability improvements to NFSD's
open file cache, and Jeff Layton contributed a menagerie of
repairs to NFSD's NFSv4 callback / backchannel implementation.

Mike Snitzer contributed a change to NFS re-export support that
disables support for file locking on a re-exported NFSv4 mount.
This is because NFSv4 state recovery is currently difficult if
not impossible for re-exported NFS mounts. The change aims to
prevent data integrity exposures after the re-export server
crashes.

Work continues on the evolving NFSD netlink administrative API.

Many thanks to the contributors, reviewers, testers, and bug
reporters who participated during the v6.15 development cycle.
