3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: "J. Bruce Fields" <bfie...@redhat.com>
commit 39307655a1effa8d913bba054c0e985bfaca808c upstream.
Commit d5497fc693a446ce9100fcf4117c3f795ddfd0d2 "nfsd4: move rq_flavor
into svc_cred" forgot to remove cl_flavor from the client, leaving two
places (cl_flavor and cl_cred.cr_flavor) for the flavor to be stored.
After that patch, the latter was the one that was updated, but the
former was the one that the callback used.
Symptoms were a long delay on utime(). This is because the utime()
generated a setattr which recalled a delegation, but the cb_recall was
ignored by the client because it had the wrong security flavor.
