I've been thinking about this a little bit, since I could not see what the race was. Do you spot one, or are you just acting on the comment? I think the original race was that we copied over the lock, lock owner, batch, etc. Hence the race was that if someone else grabbed the lock while we were doing that copy, the fields weren't in a consistent state. But now we're just copying the pointer to the lock, so I don't think there's a race. It's just a stale comment. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
