Hi Linus-
This pull request contains fixes for a bug report that came in
at the end of the 5.16-rc period. It took some time to develop
and review the fixes. Regression tests were added or updated as
a result of this issue.
There is a crash fix and a fix for an unterminating loop between
a client and server in this set, so I'm sending these now rather
than waiting for 5.18.
These have been in linux-next for several days, but the commit
dates were updated this morning because I forgot to add Cc:
stable the first time.

NFSD: Deprecate NFS_OFFSET_MAX (2022-02-09 09:24:40 -0500)
----------------------------------------------------------------
Notable bug fixes:
Ensure that NFS clients cannot send file size or offset values that
can cause the NFS server to crash or to return incorrect or
surprising results. In particular, fix how the NFS server handles
values larger than OFFSET_MAX.
