From: Andy Adamson <andros@xxxxxxxxxx> These patches fix recovery from NFS4ERR_BAD_STATEID, NFS4ERR_ADMIN_REVOKED, and NFS4ERR_DELEG_REVOKED errors by removing the delegation record, testing the delegation stateid, and recovering via an OPEN with CLAIM_NULL. Tested with a pynfs test that removes the pynfs server delegation stateid and return NFS4ERR_BAD_STATEID upon a READ.
