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. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmLujF0ACgkQM2qzM29m f5c14w/+Lsoryo5vdTXMAZBXBNvVdXQmHqLIEotJEVA3sECr+Kad2bF8rFaCWVzS Gf9KhTetmcDO9O73I5I/UtJ2qFT9B4I6baSGpOzIkjsM/aKeEEQpbpdzPYhKrCEv bQu3P54js7snH4YV8s0I39nBFOWdnahYXaw7peqE/2GOHxaR2mz88bkrQ+OybCxz KETqUxA6bKzkOT61S0nHcnQKd8HQzhocMDtrxtANHGsMM167ngI1dw4tUQAtfAUI s9R+GS6qwiKgwGz1oqhTR6LA/h4DROxPnc7AieuD9FvuAnR3kXw61bGMN5Biwv2T JZUTBbQvWhNasSV+7qOY9nBu+sHVC6Q7OZ5C9F/KjMyqCioDX0DnbxX9uKP20CDd EAAMS8n4Tdgd4KRBWdkLXPzizWYAjZQmFIJtcZne1JzGZ4IWRnikgM5qD6n1VviZ kcPRm5EN3DRHA+Hte4jG0EHIrE/7g5gnf+zr9dWl3uNhZtfTmumCfU16YYmKG8pP QN4kXBR2w7dAvp8nRaOsY6bBFLDAk/jHbpY8Q4xoUO4tsojfWayCTGVFOrecOjxv uSn0LhiidC5pLlkcPgwemhysVywDzr+gGXBRJXeUOHfdd05Q2gbFK8OpqDSvJ3dZ aC/RxFvHc8jaktUcuIjkE6Rsz6AVaAH3EZj84oMZ4hZhyGbEreg= =PEJ3 -----END PGP SIGNATURE----- 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.
