Hey, I discussed about IKU at the Linux Linux security module
maintainers monthly meeting and we concluded that it would be nice if
this had a spread to linux-integrity and linux-security-module mailing
lists.

It is x86 feature at this point but obviously that will work as
reference model to other architectures too.  So it would be nice
if those mailing lists would be also included to the loop.

I do not have time to check if this is relevant but this I think
the last version seen of encrypted hibernate:

https://lore.kernel.org/linux-integrity/20221111231636.3748636-1-evgreen@chromium.org/

Just adding it as a reference since I mentioned it earlier.

I'm on holiday for the next week but will look forward to the next
version after I'm back.

BR, Jarkko
