Michael says that for users of modinfo, "dsa_tag-20" is not the most suggestive name, and recommends a change to "dsa_tag-id-20". Andrew points out that other modaliases have a prefix delimited by colons, so he recommends "dsa_tag:20" instead of "dsa_tag-20". To satisfy both proposals, Florian recommends "dsa_tag:id-20". The modaliases are not stable ABI, and the essential information (protocol ID) is still conveyed in the new string, which request_module() must be adapted to form.
