refcount

函数名称：_dec - decrement a refcount*@r: the refcount* Similar to atomic_dec(), it will WARN on underflow and fail to decrement* when saturated at REFCOUNT_SATURATED.* Provides release memory ordering, such that prior loads and stores are done* before.

函数原型：static inline void refcount_dec(refcount_t *r)

返回类型：void

参数：

类型	参数	名称
refcount_t *	r

296

如果此条件成立可能性小(为编译器优化)(atomic_fetch_sub_release(1, & refs) <= 1)则refcount_warn_saturate(r, REFCOUNT_DEC_LEAK)
