If mdcheck_start service can finish check action, it doesn't need to start mdcheck_continue service. So in rhel only patch mdcheck.patch, we stop mdcheck_continue timer. And there is a history problem. It needed KillMode=none before, so it removed the upstream patch 52c67fcdd. Now this problem has been fixed, so we can do the backport more easilly now. We don't need to remove the upstream patch here again. Resolves: rhbz#2116418, rhbz#2150862, rhbz#2159584 Signed-off-by: Xiao Ni <xni@redhat.com>
