Hi Andrew, these two patches are follow-up fixups for the oom detection rework. The first patch should be folded into mm-oom-rework-oom-detection.patch. I haven't noticed classzone_idx vs high_zoneidx only when working on the second patch which is a fix for !CONFIG_COMPACTION where Joonsoo reported a premature OOM killer. I didn't pay attention to this configuration before but I have tested a heavy fork load on a small machine and the patch helps as it restores the original behavior more or less for !costly high order requests. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
