struct task_struct *tsk
struct mm_struct *mm
569  bool ret = true
571  如果非rylock for reading -- returns 1 if successful, 0 if contention则
572  trace_skip_task_reaping(pid)
573  返回:false
582  如果st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from则
583  trace_skip_task_reaping(pid)
584  转到:out_unlock
587  trace_start_task_reaping(pid)
590  ret等于__oom_reap_task_mm(mm)
591  如果非ret则转到:out_finish
594  打印信息("oom_reaper: reaped process %d (%s), now anon-rss:%lukB, file-rss:%lukB, shmem-rss:%lukB\n", task_pid_nr(tsk), comm, K(per-process(per-mm_struct) statistics.), K(per-process(per-mm_struct) statistics.), K(per-process(per-mm_struct) statistics.))
599  out_finish :
600  trace_finish_task_reaping(pid)
601  out_unlock :
