函数名称：lockdep_print_held_locks

函数原型：static void lockdep_print_held_locks(struct task_struct *p)

返回类型：void

参数：

类型参数名称
struct task_struct *p
697  depth等于READ_ONCE(lockdep_depth)
699  如果非depth则printk("no locks held by %s/%d.\n", 是否使用FPU, task_pid_nr(p))
701  否则printk("%d lock%s held by %s/%d:\n", depth, depth > 1 ? "s" : "", 是否使用FPU, task_pid_nr(p))
708  如果任务状态恒等于就绪态且p不等于当前进程则返回
710  以i小于depth循环
711  printk(" #%d: ", i)
712  print_lock(held_locks + i)
