Right, so either we have it always on, for things like ftrace, in which case the creation traverses rmap and installs the probes all existing mmap()s, and a mmap() hook will install it on all new ones. Or they're strictly consumer driver, like perf, in which case the act of enabling the event will install the probe (if its not there yet).
