函数名称：match a profile and its associated ns component if needed* Assumes visibility test has already been done.* If a subns profile is not to be matched should be prescreened with* visibility test.

函数原型：static inline unsigned int match_component(struct aa_profile *profile, struct aa_profile *tp, unsigned int state)

返回类型：unsigned int

参数：
