Linus Torvalds e394ff83bb NFSD 6.0 Release Notes
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.
