How to use it with cryptsetup?
I'm asking because it is not clear to me why you are not implementing
a new kernel key type (KEYS subsystem)
to utilize tagged keys.

You're right, that would be phmac(...).
But the point is we don't want each driver to

Well if we're following the existing paes model then it'd be
cbc(paes).

Yes but it's still exactly the same

Tagged keys are keys that contain metadata indicating what
they are and how to handle them using tag_object API.
Add support, for tagged keys, to skcipher algorithms by
adding new transformations, with _tk_ prefix to distinguish
between plaintext and tagged keys.
