Could give a little more detail on why you want this? When do you
want multiple arrays on the same device to sync at the same time?
What exactly is the hardware like?
md threads generally run for a little while to perform some task, then
stop and wait to be needed again. md_wakeup_thread says "you are
needed again".
The resync/recovery thread is a bit different. It just run md_do_sync
once. md_wakeup_thread is not really meaningful in that context.
What you want is:
wake_up(&resync_wait);
that will get any thread that is waiting for some other array to
resync to wake up and see if something needs to be done.
