dm: fix second blk_delay_queue() parameter to be in msec units not jiffies
Commit d548b34b062 ("dm: reduce the queue delay used in dm_request_fn from 100ms to 10ms") always intended the value to be 10 msecs -- it just expressed it in jiffies because earlier commit 7eaceaccab ("block: remove per-queue plugging") did. Signed-off-by: Tahsin Erdogan <tahsin@google.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Fixes: d548b34b062 ("dm: reduce the queue delay used in dm_request_fn from 100ms to 10ms") Cc: stable@vger.kernel.org # 4.1+ -- stable@ backports must be applied to drivers/md/dm.c
