Merge tag 'nfs-for-5.18-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs

Pull NFS client fixes from Trond Myklebust:
 "Stable fixes:

   - SUNRPC: Ensure we flush any closed sockets before xs_xprt_free()

  Bugfixes:

   - Fix an Oopsable condition due to SLAB_ACCOUNT setting in the
     NFSv4.2 xattr code.

   - Fix for open() using an file open mode of '3' in NFSv4

   - Replace readdir's use of xxhash() with hash_64()

   - Several patches to handle malloc() failure in SUNRPC"
