[dm-devel] [PATCH 01/11] block/loop: queue ordered mode should be DRAIN_FLUSH

[Tejun Heo <tj kernel org>]

loop implements FLUSH using fsync but was incorrectly setting its
ordered mode to DRAIN.  Change it to DRAIN_FLUSH.  In practice, this
doesn't change anything as loop doesn't make use of the block layer
ordered implementation.
