[PATCH] md: possible fix for unplug problem
I have reports of a problem with raid5 which turns out to be because the raid5 device gets stuck in a 'plugged' state. This shouldn't be able to happen as 3msec after it gets plugged it should get unplugged. However it happens none-the-less. This patch fixes the problem and is a reasonable thing to do, though it might hurt performance slightly in some cases. Until I can find the real problem, we should probably have this workaround in place.
