Hi,

The loop direct I/O patches[1] have been merged to linus kernel tree
and will be released in v4.4.

So the two patches provide interfaces for using direct IO/AIO
in losetup.

 include/loopdev.h   |  4 ++++
 lib/loopdev.c       | 40 ++++++++++++++++++++++++++++++++++++++++
 sys-utils/losetup.c | 33 +++++++++++++++++++++++++++++++--

V1:
	- support to set direct IO for 'new' device, such as 
		loseutp --direct-io 1 -f test.img


Thanks,
Ming
