Um.  What are you talking about?  The entire patch was clearly derived
from mine.  Not just "one sentence from your commit log".  The title,
the pushes/pops in the prologue/epilogue, the removal of the
"ebpf_from_cbpf" argument, the code spacing, and some of the non trivial
comment changes were the same.

Wth.  I made a simple request for credit.  Anybody can see the patch was
derived from mine.  It's not like I really care.  It's just basic human
decency.
