Merge tag 'nfsd-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux

Pull nfsd updates from Chuck Lever:
"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 unresponsive 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"

NFSD: move create/destroy of laundry_wq to init_nfsd and exit_nfsd

This patch moves create/destroy of laundry_wq from nfs4_state_start
and nfs4_state_shutdown_net to init_nfsd and exit_nfsd to prevent
the laundromat from being freed while a thread is processing a
conflicting lock.

NFSD: add courteous server support for thread with only delegation

This patch provides courteous server support for delegation only.
Only expired client with delegation but no conflict and no open
or lock state is allowed to be in COURTESY state.

Delegation conflict with COURTESY/EXPIRABLE client is resolved by
setting it to EXPIRABLE, queue work for the laundromat and return
delay to the caller. Conflict is resolved when the laudromat runs
and expires the EXIRABLE client while the NFS client retries the
OPEN request. Local thread request that gets conflict is doing the
retry in _break_lease.

Client in COURTESY or EXPIRABLE state is allowed to reconnect and
continues to have access to its state. Access to the nfs4_client by
the reconnecting thread and the laundromat is serialized via the
client_lock.

"Bruce has announced he is leaving Red Hat at the end of the month and
is stepping back from his role as NFSD co-maintainer. As a result,
this includes a patch removing him from the MAINTAINERS file.

There is one patch in here that Jeff Layton was carrying in the locks
tree. Since he had only one for this cycle, he asked us to send it to
you via the nfsd tree.

There continues to be 0-day reports from Robert Morris @MIT. This time
we include a fix for a crash in the COPY_NOTIFY operation.

Highlights:
- Bruce steps down as NFSD maintainer
- Prepare for dynamic nfsd thread management
- More work on supporting re-exporting NFS mounts
- One fs/locks patch on behalf of Jeff Layton

Notable bug fixes:
- Fix zero-length NFSv3 WRITEs
- Fix directory cinfo on FS's that do not support iversion
- Fix WRITE verifiers for stable writes
- Fix crash on COPY_NOTIFY with a special state ID"
