No. It means that - gcc used to (long ago) always honor "inline", and we had kernel code that depended on that in various ways (ie required that there was no return etc). We've been mostly replacing the ones we know about with "__always_inline", but there may be some that remain. We'll find out, I guess. - gcc was a total and utter piece of horrible crap in the inlining department, doign insane things and changing their documentation to match the new behaviour (and some people then claimed that it was always documented that way). It would not inline big functions even when they statically collapsed to nothing, etc. As a result, we really couldn't afford to let gcc make any inlining decisions, because the compiler was simply *broken*.
