I sent out v3 despite the name (of course forgot that git-send-email -vX is silently
dropped when sending patch files directly..):

https://lore.kernel.org/linux-integrity/cover.9fc9298fd9d63553491871d043a18affc2dbc8a8.1626885907.git-series.a.fatoum@pengutronix.de/T/#t

I'd advise you base your changes on the first two patches there as well as the Kconfig fix/enhancement
I sent out separately:
https://lore.kernel.org/linux-integrity/20210721160258.7024-1-a.fatoum@pengutronix.de/T/#u

Those are relevant for you as well and I assume they should be good to be merged even if the
CAAM series turns out to need some more love.

Cheers,
Ahmad
