If for some reason a function is called that triggers the recursion
detection of live patching, trigger a warning. By not executing the live
patch code, it is possible that the old unpatched function will be called
placing the system into an unknown state.

It has actually been first suggested by Miroslav. He might want

I'll switch suggested by to Miroslav.
