I see. Just to clarify: does the in-kernel user requirement also
apply
to the case when the author of a device driver also provides the
software implementation for the new algorithms supported by device
driver / HW?

Yes we need an actual user.  For example, if your algorithm is used
by the Security Subsystem (IMA) that would be sufficient.

Understood, thanks!

Unrelated question: I have my Keem Bay OCS ECC patchset [1] almost
ready for re-submission. Should I go ahead or should I wait for the
final decision about using 'ecdh-nist-pXXX' in place of 'ecdh'?

Also, I guess I'll have to drop P-384 support from the driver, since
the are no in-kernel user AFAIK.
