If I include the old codepath that _does_ require root, which wouldn't
be used on newer systems (which would use the newer codepath either
way), then it would support old 2.6 kernels from 4 years ago, yes.

Whether or not I should bother doing that is the question I'm asking. It
would make the code bigger in order to support old kernels.

There are two APIs. The question is, should I include _both_ APIs, or
just the newer one (which was introduced in linux 3.0).
