Sashiko reviews for the LSM mailing list

Hi,

I've been reading Sashiko's (AI bot) reviews wrt Landlock patches, and
most of them were valuable.  It found issues (security or not), but it
requires to go to https://sashiko.dev to find them, which is too easy to
forget, and requires additional work from maintainers to copy or point
to these reviews.  I sent a PR (currently in draft) to enable email
replies from Sashiko to the Linux Security Module mailing list (most
patches are already reviewed anyway):
https://github.com/sashiko-dev/sashiko/pull/278

Making such reviews broadly available can improve the quality of patches
we receive without much noise, helping for all LSM-related code.  We can
fine tune some email-related settings if needed.

If there are any concern or question, this is the right time to start a
discussion.

Regards,
 Mickaël
