Users can stop a dirty bitmap, start backup of it, and start another
dirty bitmap atomically, so that the dirty bitmap is tracked

I probably missed that in my review for v7 because I based that on my/Kevin's block-next branch instead of Stefan's (which I'm doing now): This conflicts with Stefan's AioContext series. Now there's a .clean, so it should read:

     },
