https://lore.kernel.org/all/20220204195852.1751729-47-willy@infradead.org/
was obsoleted by commit b109b87050df

https://lore.kernel.org/all/20220204195852.1751729-48-willy@infradead.org/
and
https://lore.kernel.org/all/20220204195852.1751729-50-willy@infradead.org/
were also obsoleted by Hugh's mlock changes

I also sent
https://lore.kernel.org/all/YjJJIrENYb1qFHzl@casper.infradead.org/

but never quite got it up to submittable quality.
