Cheers,

----------------------------------------------------------------
NFS client updates for Linux 5.16
Highlights include:
Features:
- NFSv4.1 can always retrieve and cache the ACCESS mode on OPEN
- Optimisations for READDIR and the 'ls -l' style workload
- Further replacements of dprintk() with tracepoints and other tracing
improvements
- Ensure we re-probe NFSv4 server capabilities when the user does a
"mount -o remount"
Bugfixes:
- Fix an Oops in pnfs_mark_request_commit()
- Fix up deadlocks in the commit code
- Fix regressions in NFSv2/v3 attribute revalidation due to the
change_attr_type optimisations
- Fix some dentry verifier races
- Fix some missing dentry verifier settings
- Fix a performance regression in nfs_set_open_stateid_locked()
- SUNRPC was sending multiple SYN calls when re-establishing a TCP
connection.
- Fix multiple NFSv4 issues due to missing sanity checking of server
return values
- Fix a potential Oops when FREE_STATEID races with an unmount
Cleanups:
- Clean up the labelled NFS code
- Remove unused header <linux/pnfs_osd_xdr.h>
