函数名称：lock_release

函数原型：void lock_release(struct lockdep_map *lock, unsigned long ip)

返回类型：void

参数：

类型参数名称
struct lockdep_map *lock
unsigned longip
4495  如果此条件成立可能性小(为编译器优化)(lockdep_recursion)则返回
4498  raw_local_irq_save(flags)
4499  Check whether we follow the irq-flags state precisely:
4500  lockdep_recursion等于1
4501  trace_lock_release(lock, ip)
4502  如果Remove the lock from the list of currently held locks - this gets* called on mutex_unlock()/spin_unlock*() (or on a failed* mutex_lock_interruptible()).则We are building curr_chain_key incrementally, so double-check* it from scratch, to make sure that it's done correctly:
4504  lockdep_recursion等于0
4505  raw_local_irq_restore(flags)
