Hi Dave, this patch removes the lock you saw with will-it-scale/page_fault2 entirely, is there a chance you could give it a spin? It's based on v3.17-rc4-mmots-2014-09-12-17-13-4 and that memcg THP fix. That kernel also includes the recent root-memcg revert, so you'd have to run it in a memcg; which is as easy as: mkdir /sys/fs/cgroup/memory/foo echo $$ >/sys/fs/cgroup/memory/foo/tasks perf record -g -a ./runtest.py page_fault2 Thanks! -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
