| H A D | loop.h | ab1cb278 Sun Aug 16 21:31:50 CDT 2015 Ming Lei <ming.lei@canonical.com> block: loop: introduce ioctl command of LOOP_SET_DIRECT_IO
If loop block is mounted via 'mount -o loop', it isn't easy
to pass file descriptor opened as O_DIRECT, so this patch
introduces a new command to support direct IO for this case.
