Merge tag 'nfsd-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
 "This release introduces support for the CB_RECALL_ANY operation. NFSD
  can send this operation to request that clients return any delegations
  they choose. The server uses this operation to handle low memory
  scenarios or indicate to a client when that client has reached the
  maximum number of delegations the server supports.

  The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst
  support for sparse files in local filesystems and the VFS is improved.

  Two major data structure fixes appear in this release:

   - The nfs4_file hash table is replaced with a resizable hash table to
     reduce the latency of NFSv4 OPEN operations.

   - Reference counting in the NFSD filecache has been hardened against
     races.

  In furtherance of removing support for NFSv2 in a subsequent kernel
  release, a new Kconfig option enables server-side support for NFSv2 to
  be left out of a kernel build.

  MAINTAINERS has been updated to indicate that changes to fs/exportfs
  should go through the NFSD tree"
