ext4: Renumber EXT4_IOC_MIGRATE
Pick an ioctl number for EXT4_IOC_MIGRATE that won't conflict with other ext4 ioctl's. Since there haven't been any major userspace users of this ioctl, we can afford to change this now, to avoid potential problems later. Also, reorder the ioctl numbers in ext4.h to avoid this sort of mistake in the future. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
