This patch series enables a future version of tune2fs to be able to
modify certain parts of the ext4 superblock without to write to the
block device.

The first patch fixes a potential buffer overrun caused by a
maliciously moified superblock.  The second patch adds support for
32-bit uid and gid's which can have access to the reserved blocks pool.
The last patch adds the ioctl's which will be used by tune2fs.
