 "New Features:

   - Implement the Sunrpc rfc2203 rpcsec_gss sequence number cache

   - Add support for FALLOC_FL_ZERO_RANGE on NFS v4.2

   - Add a localio sysfs attribute

  Stable Fixes:

   - Fix double-unlock bug in nfs_return_empty_folio()

   - Don't check for OPEN feature support in v4.1

   - Always probe for LOCALIO support asynchronously

   - Prevent hang on NFS mounts with xprtsec=[m]tls

  Other Bugfixes:

   - xattr handlers should check for absent nfs filehandles

   - Fix setattr caching of TIME_[MODIFY|ACCESS]_SET when timestamps are
     delegated

   - Fix listxattr to return selinux security labels

   - Connect to NFSv3 DS using TLS if MDS connection uses TLS

   - Clear SB_RDONLY before getting a superblock, and ignore when
     remounting

   - Fix incorrect handling of NFS error codes in nfs4_do_mkdir()

   - Various nfs_localio fixes from Neil Brown that include fixing an
     rcu compilation error found by older gcc versions.

   - Update stats on flexfiles pNFS DSes when receiving NFS4ERR_DELAY

  Cleanups:

   - Add a refcount tracker for struct net in the nfs_client

   - Allow FREE_STATEID to clean up delegations

   - Always set NLINK even if the server doesn't support it

   - Cleanups to the NFS folio writeback code

   - Remove dead code from xs_tcp_tls_setup_socket()"
