But I found some functions which in your patch([PATCH v13 3/7] mm, oom: cgroup-aware OOM killer) does not exist in the upstream kernel. Which version of the kernel do you patch on? And, do you have the latest patchset? The faults in PATCH v13 3/7: 1. mm/oom_kill.o: In function `out_of_memory': /linux/mm/oom_kill.c:1125: undefined reference to `alloc_pages_before_oomkill' 2. mm/oom_kill.c: In function ‘out_of_memory’: mm/oom_kill.c:1125:5: error: ‘struct oom_control’ has no member named ‘page’ oc->page = alloc_pages_before_oomkill(oc); ^ Best wishes
