函数名称：avc_xperms_audit

函数原型：static inline int avc_xperms_audit(struct selinux_state *state, unsigned int ssid, unsigned int tsid, u16 tclass, unsigned int requested, struct av_decision *avd, struct extended_perms_decision *xpd, u8 perm, int result, struct common_audit_data *ad)

返回类型：int

参数：

unsigned intssid
unsigned inttsid
u16tclass
unsigned intrequested
struct av_decision *avd
struct extended_perms_decision *xpd
u8perm

struct common_audit_data *ad
422  audited等于avc_xperms_audit_required(requested, avd, xpd, perm, result, & denied)
424  如果此条件成立可能性大(为编译器优化)(!audited)则返回:0
426  返回:This is the slow part of avc audit with big stack footprint
