The advantage of compiler warnings really is that they get caught quicker and developers will react to them much better. They might cause the code to be properly re-organized or rewritten to be much nicer, for example. The "trivial tree" kind of fixups for random other issues that get noticed separately tend to be much more about "work around issue". It might be the proper fix, of course, but it didn't end up being taken into account when writing the code, so it often ends up being just a "papering over the warning" kind of fix. Particularly since the person trying to fix the problem generally isn't the main developer of that code. Linus
