Lukas has raised the same question for ext4.
Both xfs(XFS_IOC_SWAPEXT) and ext4(EXT4_IOC_MOVE_EXT) has ioctls which uses
almost similar kind of structure as struct mov_data.
As such, there seems to be possiblity for sharing basic code (I will try)
used for sanity checking in IOC_MOV_DATA to be shared with these ioctls
but the core functionality code will remain different.

Thanks!
