[PATCH] md: make sure mdthreads will always respond to kthread_stop
There are still a couple of cases where md threads (the resync/recovery thread) is not interruptible since the change to use kthreads. All places there it tests "signal_pending", it should also test kthread_should_stop, as with this patch.
