That oom log shows 12 ooms but no tasks actually appear to be getting 
killed (there're no "Killed process 1234 (task)" found).  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.

Can you explain why Xorg is preferred as a baseline to kill rather than 
krunner in your example?

Thanks.
