| Subject: Btrfs: add missing brelse when superblock checksum fails |
| |
| From: Anand Jain <anand.jain@oracle.com> |
| |
| commit b2acdddfad13c38a1e8b927d83c3cf321f63601a upstream. |
| |
| Looks like oversight, call brelse() when checksum fails. Further down the |
| code, in the non error path, we do call brelse() and so we don't see |
| brelse() in the goto error paths. |
