类型参数名称
void *arg
608  VERBOSE_TOROUT_STRING("torture_stutter task started")
609  循环
610  如果非Is it time for the current torture test to stop?且stutter大于1则
611  wtime等于stutter
612  如果stutter大于HZ加1则
618  WRITE_ONCE(stutter_pause_test, 2)
619  We can use __set_current_state() here because schedule_timeout() calls* schedule() unconditionally.
621  WRITE_ONCE(stutter_pause_test, 0)
622  如果非Is it time for the current torture test to stop?则We can use __set_current_state() here because schedule_timeout() calls* schedule() unconditionally.
624  Absorb kthreads into a kernel function that won't return, so that* they won't ever access module text or data again.
625  当非Is it time for the current torture test to stop?循环
626  Each kthread must wait for kthread_should_stop() before returning from* its top-level function, otherwise segfaults ensue
