Hi Arnaldo, I'm struggling to understand which branch we should base our development on. I don't see these patches in perf/core or linux-next. I saw someone mentioned tmp.perf/core as a baseline, but I can't see that branch in git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git Please let me know - it would be useful for any dev during the merge window. Thanks, John
