Merge tag 'nfsd-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux
Pull nfsd updates from Chuck Lever: "Work on 'courteous server', which was introduced in 5.19, continues apace. This release introduces a more flexible limit on the number of NFSv4 clients that NFSD allows, now that NFSv4 clients can remain in courtesy state long after the lease expiration timeout. The client limit is adjusted based on the physical memory size of the server. The NFSD filecache is a cache of files held open by NFSv4 clients or recently touched by NFSv2 or NFSv3 clients. This cache had some significant scalability constraints that have been relieved in this release. Thanks to all who contributed to this work. A data corruption bug found during the most recent NFS bake-a-thon that involves NFSv3 and NFSv4 clients writing the same file has been addressed in this release. This release includes several improvements in CPU scalability for NFSv4 operations. In addition, Neil Brown provided patches that simplify locking during file lookup, creation, rename, and removal that enables subsequent work on making these operations more scalable. We expect to see that work materialize in the next release. There are also numerous single-patch fixes, clean-ups, and the usual improvements in observability" * tag 'nfsd-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux: (78 commits) lockd: detect and reject lock arguments that overflow NFSD: discard fh_locked flag and fh_lock/fh_unlock NFSD: use (un)lock_inode instead of fh_(un)lock for file operations NFSD: use explicit lock/unlock for directory ops NFSD: reduce locking in nfsd_lookup() NFSD: only call fh_unlock() once in nfsd_link() NFSD: always drop directory lock in nfsd_unlink() NFSD: change nfsd_create()/nfsd_symlink() to unlock directory before returning.
