Maybe.
But we must remember that using the flag means that multipath can't
use message during flushing I/Os, although I'm not sure how it hurts us.

If we'd like to keep the ability to use message during flushing I/Os,
we should use another flag for this purpose and set it after
dm_wait_for_completion().

Thanks,
Kiyoshi Ueda
