A task woken from a semaphore, a signal wait, a message queue or an event wait gets its timeout watchdog cancelled, but most waiters set none, and wd_cancel() then only takes the critical section to find that out. Check WDOG_ISACTIVE() first at these call sites. Each already holds the critical section, so wd_expiration() cannot be running the watchdog on another CPU and the check is exact on SMP too. wd_cancel() itself keeps its locked check.
