Subject: [PATCH] ext4: Fix 64bit feature
As per ext4 specification:
> In ext2, ext3, and ext4 (when the 64bit feature is not enabled), the
> block group descriptor was only 32 bytes long and therefore ends at
> bg_checksum. On an ext4 filesystem with the 64bit feature enabled, the
> block group descriptor expands to at least the 64 bytes described below;
> the size is stored in the superblock.
Since block group descriptor has been expanded to 64 bytes long (when 64
bit feature is enabled), we cannot index ext2_group_desc and return it
*directly* -- as we did it in ext2_get_group_desc -- it's still 32 bytes
long.
Instead, use s_desc_size field from superblock to correctly index and
return block group descriptors.

<Description>Lightweight bootloaders for floppy media (SYSLINUX), network booting (PXELINUX), and bootable "El Torito" CD-ROMs (ISOLINUX). The project also includes MEMDISK, a tool to boot legacy operating systems (such as DOS) from nontraditional media; it is usually used in conjunction with PXELINUX and ISOLINUX.</Description>
