Subject: md: make sure GET_ARRAY_INFO ioctl reports correct "clean" status
From: NeilBrown <[email protected]>
commit 9bd359203210efeb5d8f0d81c155079f34b47449 upstream.
If an array has a bitmap, the when we set the "has bitmap" flag we
incorrectly clear the "is clean" flag.
"is clean" isn't really important when a bitmap is present, but it is
best to get it right anyway.
