5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chuck Lever <chuck.lever@xxxxxxxxxx>
[ Upstream commit 5a01c805441bdc86e7af206d8a03735cc9394ffb ]
Now that the nfsd_fh_verify_err() tracepoint is always called on
error, it needs to handle cases where the filehandle is not yet
fully formed.
Fixes: 93c128e709ae ("nfsd: ensure we always call fh_verify_error tracepoint")
