类型参数名称
struct unwind_state *state
33  static bool dumped_before = false
34  bool prev_zero, zero = false
36  struct stack_info stack_info = {0}
37  visit_mask等于0
39  如果dumped_before则返回
42  dumped_before = true
44  Special printk facility for scheduler/timekeeping use only, _DO_NOT_USE_ !
48  以sp循环
50  如果get_stack_info(sp, task, & stack_info, & visit_mask)则退出
53  以sp小于end循环
55  word等于Use READ_ONCE_NOCHECK() instead of READ_ONCE() if you need* to hide memory access from KASAN.( * sp)
57  prev_zero等于zero
58  zero等于word恒等于0
