Yes, that's a good point. I wonder if we can slightly change that
rule. That link points to a thread where we discussed various
approaches to the problem, what would work, what wouldn't and why;
there is some valuable feedback there. The "8250-fix-locks-v2.patch"
link, on the other hand, points to nothing valuable.
