返回类型：unsigned int

参数：

类型参数名称
unsigned intrequested
struct av_decision *avd
struct extended_perms_decision *xpd
u8perm
intresult
unsigned int *deniedp
392  denied等于requested按位与allowed的反
393  如果此条件成立可能性小(为编译器优化)(denied)则
394  audited等于denied按位与auditdeny
395  如果audited且xpd则
396  如果avc_xperms_has_perm(xpd, perm, XPERMS_DONTAUDIT)则audited与等于requested的反
399  否则如果result则
400  audited等于denied等于requested
401  否则
402  audited等于requested按位与auditallow
403  如果audited且xpd则
404  如果非avc_xperms_has_perm(xpd, perm, XPERMS_AUDITALLOW)则audited与等于requested的反
409  deniedp等于denied
410  返回:audited
