I know this has been merged, this probably not worth of fixing it,
but the "required" is misleading when we detect via EOPNOTSUPP and EINVAL
and thus not use .min_kver. If it was due possible backport,
thus it should have been e.g. "functionality has been merged in kernel v5.5".

OT: we may lack something in the API, when function like this need to be
defined.

Kind regards,
