* USE WITH EXTREME CAUTION!

* Allows patch authors to bypass the activeness safety check at patch
* load time. Do this ONLY IF 1) the patch application will always/likely
* fail due to the function being on the stack of at least one thread at

* WARNING: Use of this macro will prevent the patch module from ever being
* rmmod'ed, though it can still be disabled. This is because the patched
* function may still be in use after disabling it. This means you can "kpatch
* unload" it, but you can't do a "kpatch load" of the same module again later
* on.
