There shouldn't be any significant performance regressions.  From my
observations, +/-1Mbps in throughput is quite possible due to cache-
effects.

Ah, OK, sorry about that.  After the automated error reports, I waited
for a day or two and after not seeing any further feedback, I figured
it'd be fine to add to the series.

I take it that as long as a patch shows up in patchworks with a
state==Action required, I should assume the patch is being worked on
(or will be worked on).

I'm not planning on adding more patches.
