| Subject: Btrfs: fix uninit variable in clone ioctl |
| |
| From: Chris Mason <clm@fb.com> |
| |
| commit de249e66a73d696666281cd812087979c6fae552 upstream. |
| |
| Commit 0d97a64e0 creates a new variable but doesn't always set it up. |
| This puts it back to the original method (key.offset + 1) for the cases |
| not covered by Filipe's new logic. |
