Ask HN: Why the LKML has only a few comments on sched BPF RFC patch?

The RFC patch [1] which introduces scheduler BPF into the Linux has been posted to the related mailing list (bpf and linux-kernel) two mounths ago. However, it has since only got a few comments [1][2].<p>To me, as a kernel-newbie, it is an interesting patch, as it enables profiling the scheduler with small overhead, changing the scheduler decision, and has barely observable overhead (NOP instruction) when no BPF programs are loaded.<p>Does anyone know why the discussion is so quiet?<p>Thanks!<p>[1] https:&#x2F;&#x2F;lore.kernel.org&#x2F;bpf&#x2F;20210916162451.709260-1-guro@fb.com&#x2F; [2] https:&#x2F;&#x2F;lwn.net&#x2F;Articles&#x2F;873244&#x2F;
