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"
