  NFSD: Handle new xprtsec= export option (2023-04-27 18:49:24 -0400)

----------------------------------------------------------------
NFSD 6.4 Release Notes

The big ticket item for this release is support for RPC-with-TLS
[RFC 9289] has been added to the Linux NFS server. The goal is to
provide a simple-to-deploy, low-overhead in-transit confidentiality
and peer authentication mechanism. It can supplement NFS Kerberos
and it can protect the use of legacy non-cryptographic user
authentication flavors such as AUTH_SYS. The TLS Record protocol is
handled entirely by kTLS, meaning it can use either software
encryption or offload encryption to smart NICs.

Work continues on improving NFSD's open file cache. Among the many
clean-ups in that area is a patch to convert the rhashtable to use
the list-hashing version of that data structure.
