Thanks for double checking! It's good that follow up fixes didn't fall
through cracks. Anyway I have to say that I find merging shortly after a
non-trivial rebase as risky and rushed through. I am not really
convinced this is so urgent to warrant such a step.

I hoped to get to it eventually and give it a deeper review because this
is a non trivial stuff. I am sorry but I couldn't have done that yet
(busy with other stuff and being OOO for quite some time).

I verified them. The rebase contents are identical to the manual merge
I did between my dev branch and hmm.git before sending them to Andrew.
So no lingering surprises that I can see.

It looks to me from the patches that Andrew updated them with

  https://lore.kernel.org/linux-mm/20190715081549.32577-2-osalva...@suse.de/

and

  https://lore.kernel.org/linux-mm/20190718120543.GA8500@linux/

so it looks good to me.

But that's just from reading the patches, I might have missed
something and I don't see the history.

Has this been properly reviewed after the last rebase and is this
actually ready for merging? I have seen some follow up fixes
http://lkml.kernel.org/r/20190715081549.32577-1-osalva...@suse.de
and do not see those patches being in the pipe line. Or have they been
merged?
