Neil Brown pointed me to this old thread:

We see that many of the prerequisites are in v5.11-rc, but
alloc_page_bulk() is not. I tried forward-porting 4/4 in that
series, but enough internal APIs have changed since 2017 that
the patch does not come close to applying and compiling.

I forgot that this was never merged.  It is sad as Mel showed huge
improvement with his work.

I'm wondering:

a) is there a newer version of that work?

Mel, why was this work never merged upstream?

Lack of realistic consumers to drive it forward, finalise the API and
confirm it was working as expected. It eventually died as a result. If it
was reintroduced, it would need to be forward ported and then implement
at least one user on top.
