Now that we know that tree works, I'm curious also now if you can
confirm just re-ordering the patches still works (it should)

https://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux.git/log/?h=20230319-module-alloc-opts-adjust

And although it's *probably* just noise, but I'm very curious how much,
if any difference there is if you just revert "module: use
list_add_tail_rcu() when adding module".

The data on that commit log is pretty small as I have a low end system,
and I'm not yet done beating the hell out of a system with stress-ng,
but getting some data froma  pretty large system would be great.
Specially if this series seems to prove fixing boot on them.
