The discussion was on patch 0, i.e. the next message in Lore's tree
view -- I would suggest adding it to the commit message for reference:

Link: https://lore.kernel.org/rust-for-linux/CANiq72k-PdSH2BNgbq=X+FhpyEErifSCKfO5ObXz6bu9_J8+fA@xxxxxxxxxxxxxx/

Anyway, since Nathan already applied it, and I see a couple patches on
top, no big deal if it cannot be added.

Thanks!

Cheers,
