Hi,
while trying to get rid of 'could sleep with mutex' messages a question occured to me: is there any global mechanism that ensures that no two threads enter the interface attach/detach functions at the same time? If there is, there should be a hint in driver(9) probably. If there isn't what is the canonical way to implement an MP-safe attach function? Some drivers use foo_attach(...) { mtx_init(&sc->mtx, ... mtx_lock(&sc->mtx); ... but this really doesn't help.
