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.
