SubjectRe: Driver Model 2 Proposal - Linux Kernel Performance v Usability


You missed a key point, the kernel people do not give a damn about binary
modules and think they are evil. They do not care if a binary module
works at all. If they can break it they will. You are wasting time and
electrons, or just pee'ng in the wind.

The only solution is to created a GPL pre-loading module with all the
GPL_ONLY needed extentions re-exported or externed as to bypass the horse

What I am shocked to see is how people are being nice to you and not
blasting you with a carpet bomb attack. I guess they are waiting to line
up on me.
