  nfs: Add missing release on error in nfs_lock_and_join_requests() (2025-04-02 09:53:16 -0400)

----------------------------------------------------------------
NFS client updates for Linux 6.15

Highlights include:

Bugfixes:
- 3 Fixes for looping in the NFSv4 state manager delegation code.
- Fix for the NFSv4 state XDR code from Neil Brown.
- Fix a leaked reference in nfs_lock_and_join_requests().
- Fix a use-after-free in the delegation return code.

Features:
- Implemenation of 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().
