And I'm saying we should have a equivalent software scheduler in the kernel that can implement this if the hardware offloaded version isn't present. It overlaps existing functionality to a certain extent, and there is no real reason for that overlap to exist. The question is which (the existing facilities or the new one) subsumes which.
