lock_acquire

函数名称：We are not always called with irqs disabled - do that here,* and also avoid lockdep recursion:

函数原型：void lock_acquire(struct lockdep_map *lock, unsigned int subclass, int trylock, int read, int check, struct lockdep_map *nest_lock, unsigned long ip)

返回类型：void

参数：

类型	参数	名称
struct lockdep_map *	lock
unsigned int	subclass
int	trylock
int	read
int	check
struct lockdep_map *	nest_lock
unsigned long	ip

4476

如果此条件成立可能性小(为编译器优化)(lockdep_recursion)则返回

4479

raw_local_irq_save(flags)

4480

Check whether we follow the irq-flags state precisely:

4482

lockdep_recursion等于1

4483

trace_lock_acquire(lock, subclass, trylock, read, check, nest_lock, ip)

4484

This gets called for every mutex_lock*()/spin_lock*() operation

4486

lockdep_recursion等于0

4487

raw_local_irq_restore(flags)
