-Add some debug information:
-mb_find_extent: mb_find_extent block=41, order=0 needed=64 next=0 ex=0/41/1@3735929054 64 64 7
-block_bitmap: ff 3f 0c 00 fc 01 00 00 d2 3d 00 00 00 00 00 00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
-
-Acctually, blocks per group is 64, but block bitmap indicate at least has
-128 blocks. Now, ext4_validate_block_bitmap() didn't check invalid block's
-bitmap if set.
-To resolve above issue, add check like fsck "Padding at end of block bitmap is
-not set".
