I had previously sent them to Michal and cc:kbuild, but Michal has not picked them up yet hence I've sent them to lkml now. It's not clear to me if Michal is the person responsible for recordmcount changes, but I initially posted this to kbuild as this is where all of your dead code & data elimination patches were going through.
Michal - do you plan to pick up these changes or would they need to be acked/merged by somebody else?
thanks, Marcin
