Linus Torvalds 6d29d7fe4f NFSD 5.19 Release Notes
We introduce "courteous server" in this release. Previously NFSD
 would purge open and lock state for an unresponsive client after
 one lease period (typically 90 seconds). Now, after one lease
 period, another client can open and lock those files and the
 unresponsive client's lease is purged; otherwise if the unrespon-
 sive client's open and lock state is uncontended, the server retains
 that open and lock state for up to 24 hours, allowing the client's
 workload to resume after a lengthy network partition.
 
 A longstanding issue with NFSv4 file creation is also addressed.
 Previously a file creation can fail internally, returning an error
 to the client, but leave the newly created file in place as an
 artifact. The file creation code path has been reorganized so that
 internal failures and race conditions are less likely to result in
 an unwanted file creation.
 
 A fault injector has been added to help exercise paths that are run
 during kernel metadata cache invalidation. These caches contain
 information maintained by user space about exported filesystems.
 Many of our test workloads do not trigger cache invalidation.
 
 There is one patch that is needed to support PREEMPT_RT and a fix
 for an ancient "sleep while spin-locked" splat that seems to have
 become easier to hit since v5.18-rc3.
