Ah, those are the swcounter and other probe entry points. I've had
several cases where we called into the perf counter code from those
points before it was initialized, getting in kernel segfaults due to
dereferencing uninitialized data etc..

I could keep a variable that tracked the perf_counter_init() state, and
use that instead if you prefer?
