Name: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

Proto:static inline void invalidate_tss_limit(void)

Type:void

Parameter:Nothing

329  DEBUG_LOCKS_WARN_ON(preemptible())
331  If Value for the false possibility is greater at compile time(test_thread_flag(uses I/O bitmap )) Then force_reload_TR()
333  Else this_cpu_write(__tss_limit_invalid, true)
