And while at it, I realized we could actually pre-populate autoksyms.h very early on with the content of the whitelist instead of having it empty. That way, there's a whole lot of things that will be compiled 'correctly' from the start (that is, adjust_autoksyms.sh won't need to re-compile them later on). And in fact, if all symbols used by in-tree modules happen to already be on the whitelist, you'll build a trimmed kernel in a single pass, which should improve build time a bit I hope. I'll add something to v3 in addition to your suggestion. Thanks, Quentin
