函数名称:__mutex_unlock_slowpath
函数原型:static noinline void __sched __mutex_unlock_slowpath(struct mutex *lock, unsigned long ip)
返回类型:void
参数:
类型 | 参数 | 名称 |
---|---|---|
struct mutex * | lock | |
unsigned long | ip |
1224 | struct task_struct * next = NULL |
1228 | mutex_release( & dep_map, ip) |
1237 | owner等于atomic_long_read( & owner) |
1238 | 循环 |
1246 | 如果owner按位与MUTEX_FLAG_HANDOFF则退出 |
1249 | old等于atomic_long_cmpxchg_release( & owner, owner, __owner_flags(owner)) |
1261 | 加自旋锁 |
1262 | debug_mutex_unlock(lock) |
1263 | 如果非链表为空则 |
1271 | debug_mutex_wake_waiter(lock, waiter) |
1278 | 自旋锁解锁 |
