Subject[PATCH 18/49] ext4: sync up block group descriptor with e2fsprogs.
Date
From: Coly Li <coyli@suse.de>

This patch extends bg_itable_unused of ext4 group descriptor
from 16bit into 32bit. In order to add bg_itable_unused_hi into
struct ext4_group_desc, some extra fields which are already introduced into
e2fsprogs are also added in for consistency.
