Here's an answer to that, also from upthread:

https://lkml.kernel.org/r/20200316180303.GR2156@tucnak

Btw lore.kernel.org has this cool mbox.gz feature:

https://lore.kernel.org/lkml/20200316180303.GR2156@tucnak/t.mbox.gz

This way, you can grep the whole thread, open it with a proper mail
program etc. Very useful for catching up on threads.

Thx.
