| Subject: dm snapshot: fix freeing pending exception |
| |
| Fix oops when removing full snapshot |
| kernel bugzilla bug 7040 |
| |
| If a snapshot became invalid (full) while there is outstanding |
| pending_exception, pending_complete() forgets to remove |
| the corresponding exception from its exception table before freeing it. |
| |
| Already fixed in 2.6.19. |
