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
