And Andi, before this goes any further, I'd like to say that (a) no, I
don't hate you and (b) sorry in advance and in retrospect for my obviously
abrasive personality and just being harsh.

In particular, this is something that I have gone through with a _lot_ of
maintainers. So you don't need to feel bad about it. Ingo and Thomas
obviously did the very same thing not that long ago.

And Davem had the same issue in the networking tree - most of the times
when I pulled, I could tell that he had _just_ rebased the whole series,
and I just knew that it had gotten effectively zero testing in that
particular configuration.

For other trees it's still ongoing: you can generally trivially tell by
looking at the merges and the dates of the commits relative to them and
'base' they are done on top of.

So you're definitely not alone. There are people who have done the same
thing, and in many cases they did it for months. I'll happily try to help
you with any git issues, and we can even change git itself to help with
some things (historically we certainly have - I certainly hope that the
need for it is going away, though).

And I can also report that the people who then re-learnt their workflow
and got used to maintaining several queues and not always working at the
top of the tree and rebasing on top of whatever "random Linus kernel of
the moment" (in order to actually work with and test what they eventually
ask me to pull!) have so far been pretty enthusiastic about the workflow
they learn once they pick it up.

And to give them credit for being smarter them me, others (like Jeff)
started doing the whole "many different branches" thing long before I
personally even realized how helpful it is.

And as mentioned, some still use the "queue on top of the most recent
version" model, and when it's something fairly far away in the periphery
and doesn't impact others, I don't really care. If it hadn't been for the
PCI merge bringing up the issue, I'd have ignored the ACPI case too.
