Oops, that was wrong.  net_prio_subsys_id itself becomes constant.
Let's please better explain why the RCU trick removal is safe then.

In the last paragraph in the commit message I tried to document why
it is safe to remove the RCU trick. Not good enough?

It isn't clear to me why it was necessary before and why it now
becomes unnecessary.  It states what the code does and that it's no
longer necessary but I'd really like more elaboration.

Got it. I'll try to document then why it was necessary before. I'll add then also the original author of those lines to the Cc list just in case I get it wrong.

cheers,
daniel
