"Bug fixes and regressions for ext4, the most serious of which is a
potential deadlock during directory renames that was introduced during
the merge window discovered by a combination of syzbot and lockdep"

Instead, the superblock and a single block group descriptor block is placed at the beginning of the first, second, and last block groups in a meta-block group. A meta-block group is a collection of block groups which can be described by a single block group descriptor -block. Since the size of the block group descriptor structure is 32 -bytes, a meta-block group contains 32 block groups for filesystems with -a 1KB block size, and 128 block groups for filesystems with a 4KB +block. Since the size of the block group descriptor structure is 64 +bytes, a meta-block group contains 16 block groups for filesystems with +a 1KB block size, and 64 block groups for filesystems with a 4KB blocksize. Filesystems can either be created using this new block group descriptor layout, or existing filesystems can be resized on-line, and the field s_first_meta_bg in the superblock will indicate the first |
