I looked over the patch series. It's rather big change of OOM. I see you and David want to make OOM fresh from scratch. But, It makes for testers to test harder. I like your idea of fork-bomb detector. Don't we use it without big change of as-is OOM heuristic? Anyway,I need time to dive the code and test it. Maybe weekend. Thanks for great effort. :) On Mon, Nov 2, 2009 at 4:22 PM, KAMEZAWA Hiroyuki wrote: > Hi, as discussed in "Memory overcommit" threads, I started rewrite. > > This is just for showing "I started" (not just chating or sleeping ;) > > All implemtations are not fixed yet.
