Theodore Ts'o 310eba0dfc ext4: fix false negatives *and* false positives in ext4_check_descriptors() ... commit 44de022c4382541cebdd6de4465d1f4f465ff1dd upstream. Ext4_check_descriptors() was getting called before s_gdb_count was initialized. So for file systems w/o the meta_bg feature, allocation bitmaps could overlap the block group descriptors and ext4 wouldn't notice. For file systems with the meta_bg feature enabled, there was a fencepost error which would cause the ext4_check_descriptors() to incorrectly believe that the block allocation bitmap overlaps with the block group descriptor blocks, and it would reject the mount. Fix both of these problems.
