  Greetings Linus-

You may notice that towards the end of the commit list in this series
the CommitDate on individual commits is December 10. I had to drop a
patch from the middle of this series due to regressions.

Its replacement and a fix for the recent server-to-server copy crasher
will be on your virtual doorstep before the v6.2 merge window closes.

Meanwhile the remaining patches below have been percolating in
linux-next for quite some time. Please pull these for v6.2.


PR follows:


The following changes since commit b7b275e60bcd5f89771e865a8239325f86d9927d:

  NFSD: Avoid clashing function prototypes (2022-12-10 11:01:13 -0500)

----------------------------------------------------------------
NFSD 6.2 Release Notes

This release introduces support for the CB_RECALL_ANY operation.
NFSD can send this operation to request that clients return any
delegations they choose. The server uses this operation to handle
low memory scenarios or indicate to a client when that client has
reached the maximum number of delegations the server supports.

The NFSv4.2 READ_PLUS operation has been simplified temporarily
whilst support for sparse files in local filesystems and the VFS is
improved.

Two major data structure fixes appear in this release:

* The nfs4_file hash table is replaced with a resizable hash table
  to reduce the latency of NFSv4 OPEN operations.

* Reference counting in the NFSD filecache has been hardened against
  races.

In furtherance of removing support for NFSv2 in a subsequent kernel
release, a new Kconfig option enables server-side support for NFSv2
to be left out of a kernel build.

MAINTAINERS has been updated to indicate that changes to fs/exportfs
should go through the NFSD tree.
