Matthew, what is a "profile"?  Could we rename this patch to something
clearer?  Maybe something like "support for per policy rule template
formats"?

Sounds good to me. Could you also add an Inspired-By: Roberto Sassu

Thanks, done.

Thanks Matthew.

If the patch it is not merged yet, please define and initialize the
template_name variable in ima_policy_show() as the same as in
ima_measurement_show().

The policy rule processing should prevent loading a custom policy with
a template rule, without specifying a valid template name.  Why does
ima_policy_show() need to initialize entry->template->name?

The last element of builtin_templates is reserved for a custom format
that can be specified with the ima_template_fmt= kernel option. This
last element has name length equal to zero. It can be found by
lookup_template_desc() if specified in a policy rule.
