[PATCH] md: tidy up device-change notification when an md array is stopped (0d4ca600) · Commits · 戴 / test

An md array can be stopped leaving all the setting still in place, or it can torn down and destroyed. set_capacity and other change notifications only happen in the latter case, but should happen in both. Signed-off-by:
