函数名称：If you do something evil that corrupts the cached TSS limit (I'm looking* at you, VMX exits), call this function.* The optimization here is that the TSS limit only matters for Linux if the* IO bitmap is in use

函数原型：static inline void invalidate_tss_limit(void)

返回类型：void

参数：无

329  DEBUG_LOCKS_WARN_ON(preemptible())
331  如果此条件成立可能性小(为编译器优化)(test_thread_flag(uses I/O bitmap ))则force_reload_TR()
333  否则抢占保护下的写CPU(__tss_limit_invalid, true)
