We have include/linux/device-mapper.h, include/linux/dm-io.h, 
include/linux/dm-kcopyd.h, include/linux/dm-region-hash.h, 
include/linux/dm-dirty-log.h. So why not include/linux/dm-bufio.h?

BTW. dm-bufio doesn't really depend on device mapper at all and it could 
be used by non-dm drivers as well.

But that mering will take a lot of time and until it happens, it will be 
distributed as a separate module.
