Merge tag 'nfsd-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever:
"New features:
- NFSv3 support in NFSD is now always built
- Added NFSD support for the NFSv4 birth-time file attribute
- Added support for storing and displaying sockaddrs in trace points
- NFSD now recognizes RPC_AUTH_TLS probes
Performance improvements:
- Optimized the svc transport enqueuing mechanism
- Added micro-optimizations for the duplicate reply cache
Notable bug fixes:
- Allocation of the NFSD file cache hash table is more reliable"
