Interesting patch!
One query; I may be being a bit dumb, I'm only just recovering from a
bad cold, but anyway... Your patch checks for a thread unlocking
mutexes in the reverse order that it locked them in (let's call this
point "A"). But I thought your recent investigations had shown that
the problem was threads doing locking in inconsistent order, e.g.
thread 1 locks M1 and then M2, while thread 2 locks M2 and then M1
(point "B"). Are points "A" and "B" equivalent? (It isn't obvious to
me if so.)
Regards,
Neil
