I'm definitely happy for you.

who said there was a problem ?

Already known and obvious, thanks. But that's unrelated to the initial post.

A makefile is userspace too. I still fail to see your point.

Huh? drinking before posting does no good it seems... :-)

Steve proposed a simple patch to ease modules compression during the
build process. Obviously it's userspace (as all the build process,
mind you). And there's nothing dirty nor funny there. Maybe you just
don't understand what it's useful for, but in this case it simply means
you don't need this feature :-)
