I pushed this to my for-linus branch, which I intend to merge for v4.0. You can browse it here to see if you agree: https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/log/?h=for-linus Dave, I know you weren't happy with this proposal the first time around, but I'm not sure why. If you have a better idea, let me know.
