Hi Thomas,

seconding the same question: any chance local lock api can be sent upstream
soon? If api skeleton can get in during this merge window we will have the next
bpf-next/net-next cycle to sort out details. If not the bpf+rt would need to
wait one more release. Not a big deal. Just trying to figure out a time line
when can we start working on concrete bpf+rt patches.
