Xishi Qiu fa8dd8a92d memory-failure: do code refactor of soft_offline_page() ... There are too many return points randomly intermingled with some "goto done" return points. So adjust the function structure, one for the success path, the other for the failure path. Use atomic_long_inc instead of atomic_long_add.
