Oh, ok. I think I know which patch from Oleg you're talking about.

Since I do want that patch too, and since I'd hate to cause
unnecessary merge conflicts in this area, how about we just plan on
letting your original patch (on top of Oleg's) go through Andrew and
the -mm tree? I'll get it that way, and it's not like this is
timing-critical.

Having to fix up conflicts in this area would just be annoying, and
would be nasty for back-porting too.
