This also adds some stricter checking of blocks to be freed in ext4_mb_clear_bb(), ext4_group_add_blocks() & ext4_mb_mark_bb(). I have tested this with few different fast_commit configs and normal 4k config with -g log,quick. Haven't seen any surprises there. RFC -> v1: ========== 1. Added Patch-1 which correctly accounts for flex_bg->free_clusters. 2. Addressed review comments from Jan 3. Might have changed the order of patches a bit.
