Thank you for your valuable feedback! Maybe you have noticed that I haven't enforced the patch and led others to decide the final name (either by resubmitting patches or a simple replace in mmotm tree). Or maybe you haven't because you are so busy bikesheding that you can hardly see anything else. > Andrew, everyone and their dog agrees MAP_FIXED_SAFE is stupid name, > but Michal decided to just go ahead, ignoring feedback... > > Can you either s/MAP_FIXED_SAFE/MAP_FIXED_NOREPLACE/g or drop the patches? You have surely saved the world today and I hardly find words to thank you (and your dog of course). Thanks! -- Michal Hocko SUSE Labs
