4086  first_idx等于idx
4088  如果DEBUG_LOCKS_WARN_ON(!已禁止中断())则返回:0
4091  以idx小于depth循环
4099  当:This gets called for every mutex_lock*()/spin_lock*() operation恒等于0
4100  返回:1
4101  当:This gets called for every mutex_lock*()/spin_lock*() operation恒等于1
4102  退出
4103  当:This gets called for every mutex_lock*()/spin_lock*() operation恒等于2
4104  merged加等于idx恒等于first_idx
4105  退出
4106  默认
4107  WARN_ON(1)
