Adding this to igt_core with a cleanup handler sounds like a plan. And really, the android lowmemkiller is just broken for aiming at processes owned by root, but apparently we can't fix that. But please add this _without_ and #ifdef ANDROID since there are linux distros out there (*cough* ubuntu *cough*) which for incomprehensible reasons add everything under CONFIG_ANDROID ... -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
