Could you also add linux-trace-kernel@vger ML to CC? ./scripts/get_maintainer.pl -f kernel/events/uprobes.c disagrees with that, also things like: https://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git/commit/?h=probes/for-next&id=4a365eb8a6d9940e838739935f1ce21f1ec8e33f touch common perf stuff, and very much would require at least an ack from the perf folks. Not cool.
