Hey folks,

Just a reminder that Samuel already did a lot of work and benchmarking
and made this a lot faster:

https://lore.kernel.org/lkml/20210523180423.108087-1-sneves@dei.uc.pt/

As far as I can tell, there was a lot of nitpicking, some of which might
have been pointless, and the author understandably didn't followup to
finish it off.

But the code and analysis is there, and maybe it'd be worthwhile for
somebody here to pick it up again?

Jason
