Subject: md: clean up irregularity with raid autodetect
From: NeilBrown <neilb@xxxxxxx>
When a raid1 array is stopped, all components currently get added to the list
for auto-detection. However we should really only add components that were
found by autodetection in the first place. So add a flag to record that
information, and use it.
