Merge tag 'nfsd-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
 "Two significant security enhancements are part of this release:

   - NFSD's RPC header encoding and decoding, including RPCSEC GSS and
     gssproxy header parsing, has been overhauled to make it more
     memory-safe.

   - Support for Kerberos AES-SHA2-based encryption types has been added
     for both the NFS client and server. This provides a clean path for
     deprecating and removing insecure encryption types based on DES and
     SHA-1. AES-SHA2 is also FIPS-140 compliant, so that NFS with
     Kerberos may now be used on systems with fips enabled.

  In addition to these, NFSD is now able to handle crossing into an
  auto-mounted mount point on an exported NFS mount. A number of fixes
  have been made to NFSD's server-side copy implementation.

  RPC metrics have been converted to per-CPU variables. This helps
  reduce unnecessary cross-CPU and cross-node memory bus traffic, and
  significantly reduces noise when KCSAN is enabled"
