Adrian Chadd 7cfecbb95b Add a witness check to enforce that no non-sleeping locks are held when ... they shouldn't be. I used this during driver bring-up to find that the Linux driver holds a whole lot of locks whilst doing their equivalent of busdma operations. If this works out well, it should be added to the other architecture busdma implementations to aid in similar debugging. Tested: * bounce buffer and dmar busdma, Lenovo X230 laptop, all the internal hardware * ath(4) too Discussed with: jhb		2016-11-03 23:11:33 +00:00
