So what do you propose in the interim? As far as io_uring is concerned,
it's not a _huge_ deal to do the IRQ dance, but it does bother me that
we're making things slightly worse for the mainline kernel just to make
the out-of-tree patches happy.

Note that the purpose of these patches are to be able to bring those
out-of-tree patches into the kernel such that they are no longer
out-of-tree.

Sure, I realize that. And I've always been accommodating to making
pieces of code more RT friendly, I just don't like doing it for cases
where we are making mainline worse.

In that regard, I do still consider those patches out-of-tree, which
they are. And while I'm more sympathetic to them compared to other
out-of-tree code as there's a long term plan to get it all in, it's
still out-of-tree. Best solution here is probably to just carry that
particular change in the RT patchset for now.
