I note that "proof" is very much in the developer's opinion and limited testing base. Actual operational experience, as in a real deployment, with other applications, heavy context switching, or virtualization, might yield better results. There's lots of defaults in the linux kernel that are just

This is vastly improved code, thank you! 1) Since we're still duking it out over the meaning of the bits - not just the SCE thing, but as best as I can tell (but could be wrong) the NQB idea wants to put something into the l4s fast queue? Or is NQB supposed to be a third queue? In those cases, th
