Aside from Hannes comment -- KCM seems to be tied to the TLS work, i.e. I have the impression that KCM without ability to do TLS in the kernel is pretty much useless for whatever use case Tom has in mind. And that ktls thing just gives me the creeps. For KCM itself I don't even get the use case -- its in the 'yeah, you can do that, but... why?' category 8-/
