Several folks reported that with v5.8-rc kernels their console is spammed with

a4fa458950b4 not pushed into bpf tree given it was affected there too? Either
way, we can undo the double pos assignment upon tree sync..

Just as a side note, please note it was more than spamming on the console.

It prevented the subsystem from working at all.
