Ok, I'll add a note to the pull request report about where the perf
build is clean in all containers because I added these two patches, but
that they'll go via the bpf tree, as soon as that gets merged, the
problem will go away.

And I wasn't strictly defending that I should carry this in perf/core,
just said I was, to fix something minor that I found while doing my
usual testing, patch was posted, you got notified and got the patch,
I'll remove it from perf/core now since you stated that it'll eventually
land upstream.

Thanks,
