| Subject: [PATCH] ceph: return ceph_mdsc_do_request() errors from |
| __get_parent() |
| |
| commit c6d50296032f0b97473eb2e274dc7cc5d0173847 upstream. |
| |
| Return the error returned by ceph_mdsc_do_request(). Otherwise, |
| r_target_inode ends up being NULL this ends up returning ENOENT |
| regardless of the error. |
