I'm all for proper review and fixing any issues before forcing
"ugliness" and "black magic" on unsuspecting users.
Having said that, you failed to mention that your company sells
userspace stack replacements.
Informal testing I did convinces me that for a given HW, the latencies
you get with this patchset and with userspace busy-polling are about the
same. (This is my personal opinion, I'm not authorized to talk on behalf
of my company or anyone else.)
Why don't you try it out and tell us what you find.
