NFSv4: Retry LOCK on OLD_STATEID during delegation return
stable inclusion from stable-v5.10.156 commit 6cb657722e37561202194bb52ba387a82572ac3f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7MCG1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6cb657722e37561202194bb52ba387a82572ac3f -------------------------------- [ Upstream commit f5ea1613 ] There's a small window where a LOCK sent during a delegation return can race with another OPEN on client, but the open stateid has not yet been updated. In this case, the client doesn't handle the OLD_STATEID error from the server and will lose this lock, emitting: "NFS: nfs4_handle_delegation_recall_error: unhandled error -10024". Fix this by sending the task through the nfs4 error handling in nfs4_lock_done() when we may have to reconcile our stateid with what the server believes it to be. For this case, the result is a retry of the LOCK operation with the updated stateid. Reported-by:Gonzalo Siero Humet <gsierohu@redhat.com> Signed-off-by:
