Merge tag 'nfs-for-6.15-1' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client updates from Trond Myklebust:
 "Bugfixes:

   - Three fixes for looping in the NFSv4 state manager delegation code

   - Fix for the NFSv4 state XDR code (Neil Brown)

   - Fix a leaked reference in nfs_lock_and_join_requests()

   - Fix a use-after-free in the delegation return code

  Features:

   - Implement the NFSv4.2 copy offload OFFLOAD_STATUS operation to
     allow monitoring of an in-progress copy

   - Add a mount option to force NFSv3/NFSv4 to use READDIRPLUS in a
     getdents() call

   - SUNRPC now allows some basic management of an existing RPC client's
     connections using sysfs

   - Improvements to the automated teardown of a NFS client when the
     container it was initiated from gets killed

   - Improvements to prevent tasks from getting stuck in a killable wait
     state after calling exit_signals()"
