-Subject: [PATCH] ext4: make sure bitmaps and the inode table don't overlap
- with bg descriptors
-
-It's really bad when the allocation bitmaps and the inode table
-overlap with the block group descriptors, since it causes random
-corruption of the bg descriptors.  So we really want to head those off
-at the pass.
