Group mutexes used in hwpmc(4) into 3 "types" in the sense of witness(4): - leaf spin mutexes---only one of these should be held at a time, so these mutexes are specified as belonging to a single witness type "pmc-leaf". - `struct pmc_owner' descriptors are protected by a spin mutex of witness type "pmc-owner-proc". Since we call wakeup_one() while holding these mutexes, the witness type of these mutexes needs to dominate that of "sleepq chain" mutexes. - logger threads use a sleep mutex, of type "pmc-sleep".
