Parent article: Another push for sched_ext

The "pull a RedHat" comment is a non sequitur. The final, best, accepted versions of every improvement or patch Red Hat makes or applies to RHEL are distributed to everyone via CentOS Stream. Interim updates may go to customers only (usually, backported patches instead of an upstream with a new version which may incorporate slightly different code), but the actual code is shared with the world.

That situation _still_ may not make everyone happy, but it'd at least be nice if people were mad about the actual thing, rather than something very different.

If Red Hat makes improvements to the scheduler, via the mainline scheduler or BPF, they'll be shared back in a way that ultimately benefits everyone, and which emphasizes upstream collaboration -- _even if_ the BPF approach would technically allow us to not do so. (If this policy changes in the future, I'll go on record as saying that I'll be one of the people angry about it.)

Red Hat has a long-standing policy of first merging the patches upstream, only then shipping them in RHEL: https://www.redhat.com/en/blog/what-open-source-upstream we call it "upstream first"

(there are exceptions, of course, like security fixes, or unresponsive upstreams, etc. but the policy is still very much to get every patch shipped merged upstream)

I like these kinds of disclaimers. They show that you are very likely to know what you're talking about, and can be treated with rather greater confidence than those who smear from the outside.

For the record, I too work at Red Hat. So, same disclaimer.

Thank you for speaking up!
