Doc Text:
.MDS no longer gets indefinitely stuck while waiting for the cap revocation acknowledgement Previously, if `__setattrx()` failed, the `_write()` would retain the `CEPH_CAP_FILE_WR` caps reference, the MDS would be indefinitely stuck waiting for the cap revocation acknowledgment. It would also cause other clients' requests to be stuck indefinitely. With this fix, the `CEPH_CAP_FILE_WR` caps reference is released if the `__setattrx()` fails and MDS' caps revoke request is not stuck.

Description Xiubo Li 2023-03-29 04:21:33 UTC 
If the __setattrx() fails it will leave the CEPH_CAP_FILE_WR caps
    reference kept.
