Why does the kernel even make that information available? I regularly have my machine made unusable when the kernel decides to kill the largest memory users (usually the mail client, or a browser tab), and it OOM kills the largest memory users, meaning the ones that will take the longest to dump to disk. We already have records of the application being killed through OOM in the journal, we should be spared even trying to pass the core to user-space. _______________________________________________ desktop mailing list -- desktop@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to desktop-leave@xxxxxxxxxxxxxxxxxxxxxxx
