Merge tag 'nfs-for-6.5-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client updates from Trond Myklebust:
"Stable fixes and other bugfixes:

   - nfs: don't report STATX_BTIME in ->getattr

   - Revert 'NFSv4: Retry LOCK on OLD_STATEID during delegation return'
     since it breaks NFSv4 state recovery.

   - NFSv4.1: freeze the session table upon receiving NFS4ERR_BADSESSION

   - Fix the NFSv4.2 xattr cache shrinker_id

   - Force a ctime update after a NFSv4.2 SETXATTR call

  Features and cleanups:

   - NFS and RPC over TLS client code from Chuck Lever

   - Support for use of abstract unix socket addresses with the rpcbind
     daemon

   - Sysfs API to allow shutdown of the kernel RPC client and prevent
     umount() hangs if the server is known to be permanently down

   - XDR cleanups from Anna"
