I was speaking of actual *users* as in indiiduals running their own
systems, companies running their own servers/datacenter.  The fact that
some ISP (or its supplier) decisdes that one of my IP packets is routed
via a smartnic with XDP offloading somewhere is great, but still doesn't
turn me into a "user" of that technology.  Not in my linke of thinking,
at least.

I am sorry that our opinions differ.

I must consider all users of Linux both direct and indirect, to
determine impact and where resources and efforts should be allocated.

And by in large, for system tracing and analysis eBPF is basically
a hard requirement for people doing anything serious these days.

That's great, but misses the point.  I was referring to usage in the
context of the kernel network stack.  Sorry for not being explicit
enough.

And that misses the point entirely.

Which is that eBPF is more than just networking, so it is missing
that this technology is not just networking specific but a kernel
wide one that is being adopted in every nook and cranny of the
kernel.

Sure, one data center / hosting / "cloud" provider can quickly roll out
a change in their network.  But I'm referring to significant,
(Linux-)industry-wide adoption.

Hehe, I guess whatever definition works for the position you are
trying to take.
