V2->V3: Replace patch 3's changelog with the one suggested by Jan Kara. Refactor the code in patch 4 to make it more readable, as suggested by Jan Kara. Patch 8 is adapted based on patch 4 after modification. Add Reviewed-by tag. V1->V2: Fixed some things pointed out by Jan Kara. Fixed more cases where blocks could be allocated from corrupted groups.
