Yes, people write to me asking for the SR-IOV patch or update everyday
-- I guess they don't want to let their competitors know they are
working on it so they can't bring their questions up on the mailing list.

And I personally also have dozen of other patches related to PCI and KVM
subsystems which depend on the SR-IOV change.
