Replace add_timer() by mod_timer() in dst_run_gc in order to avoid BUG message. CPU1 CPU2 dst_run_gc() entered dst_run_gc() entered spin_lock(&dst_lock) ..... del_timer(&dst_gc_timer) fail to get lock .... mod_timer() <--- puts timer back .... in list add_timer(&dst_gc_timer) <--- BUG because timer is in list already. Found during OpenVZ internal testing (#62581)
