| Subject: [PATCH] reiserfs: Fix spurious unlock in reiserfs_fill_super() error |
| handling |
| |
| commit 4d5c1adaf893b8aa52525d2b81995e949bcb3239 upstream. |
| |
| When we fail to allocate string for journal device name we jump to |
| 'error' label which tries to unlock reiserfs write lock which is not |
| held. Jump to 'error_unlocked' instead. |
| |
| Fixes: f32485be8397 ("reiserfs: delay reiserfs lock until journal initialization") |
