I pointed out the patches from the queue that ended upstream.
After upstream's review a few things changed like the revert of the
user/irq context and so on. For simplicity reasons I would prefer to
stick with one solution and not add the intermediate patches, that I had
in the queue before I was able to settle with upstream on something, to
release that is maintained for a longer period. So any problems that pop
in 5.15 should be same as in later releases.

The patches I mentioned ended up in v5.18 and were part of the latest
v5.17-RT releases including v5.17.1-rt17, yes.
