Subject: Kernel question: i386 test-and-set problem Date: Fri, 21 Jul 2000 09:15:44 -0400 I would have left the lock in if I could have figured out how to do it and fix the other problems. The main problem is that one side knows p and the other side knows r. If I have one lock, one side is going to have to look at something not under a lock. If I have two locks, one in r and one in p, I can't figure out how to get them both to lock in the same order.
