ext4: add bg_itable_unused_hi to group descriptor
PATCH 1/1 ext4: add bg_itable_unused_hi to group descriptor
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.
