-Subject: ext4: make sure bitmaps and the inode table don't overlap with bg
- descriptors
-Origin: https://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git/commit?id=6b506a7d09854128b1da9571d879ee9dea3ffb02
-Bug-Debian-Security: https://security-tracker.debian.org/tracker/CVE-2018-10878
-
-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.
