Just a reminder that we have x86/urgent which will be going to Linus
like today. There's also x86/mm which goes up in the next merge window..
The "Fix effective RW computation" patch is getting broken out and is
going to wait for the next merge window. We don't want it sitting in
mainline generating warnings, especially false positives like the one
this weekend. That's not to disparage the patch; it's overall the right
thing to do.
Sound good?
