Do you have any idea why? Anyway, as I posted in response to KAMEZAWA-san's patch, the change to get_mm_rss(mm) prefers Xorg more than the current implementation. >>From your log at the link above: total_vm 669624 test 195695 krunner 187342 krusader 168881 plasma-desktop 130562 ktorrent 127081 knotify4 125881 icedove-bin 123036 akregator rss 668738 test 42191 Xorg 30761 firefox-bin 13331 icedove-bin 10234 ktorrent 9263 akregator 8864 plasma-desktop 7532 krunner Can you explain why Xorg is preferred as a baseline to kill rather than krunner in your example?
