Not only does this mean they were all recently rebased, absolutely
*NONE* of this has been in linux-next as fat as I can tell. Not in a
rebased form _or_ in the pre-rebased form.

So no. This is not acceptable, you can try again next time when you do
it properly.

My notes say that I saw my two vhost: vringh  deadcode patches in -next
on 2025-07-17.

Oh. My bad.

My linux-next head was not up-to-date: I had fetched the new state,
but the branch was still pointing to the previous one.

My apologies - they are indeed there, and I was simply looking at stale state.

So while it's recently rebased, the commits have been in linux-next
and I was just wrong.

Pulled and pushed out. Sorry again for blaming Michael for my own incompetence.
