Er? Aren't dpfree/hostfree new functions? I didn't see them
added as exports in your patch, and regardless they belong in
comproc.c now.
Try this then
The problem is that on 2.6.x I have never gotten EXPORT() in commproc.c
(or anywhere else) to work, I have had to put them on ppc_ksyms.c to be
able to load my modules
I do not know if there is some magic thatI have forgotten to do.
