Just syncing up briefly after LPC: thanks ever so much for your attendance and amazingly helpful comments, the session worked because you were there :) So, I'm planning for the next version of the kallmodsyms patch series to have objfile disambiguation via {...} for otherwise-ambiguous symbols in the core kernel, but not yet in modules (because that's considerably trickier and can be incrementally added to a working kallmodsyms). I'll redo the cover letter to emphasise its role as a way to disambiguate all symbols from each other. ... was there anything else? I can't recall anything else myself and my notes don't mention anything, but I could be wrong and I'd rather not waste your time with a patch posting that is doing the wrong thing.
