nfsd4: forbid all renames during grace period
The idea here was that renaming a file on a nosubtreecheck export would make lookups of the old filehandle return STALE, making it impossible for clients to reclaim opens. But during the grace period I think we should also hold off on operations that would break delegations. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
