函数名称：avc_audit_post_callback - SELinux specific information* will be called by generic audit code*@ab: the audit buffer*@a: audit_data

函数原型：static void avc_audit_post_callback(struct audit_buffer *ab, void *a)

返回类型：void

参数：

类型参数名称
struct audit_buffer *ab
void *a
703  ad等于a
704  sad等于selinux_audit_data
709  rc等于security_sid_to_context(state, ssid, & scontext, & scontext_len)
