I'm looking at these awk scripts and od encodings and I wonder if wasn't it
simpler to write the test in C.

We have a bunch of helpers in tools/testing/selftests/mm/vm_utils.h for
accessing /proc files and there is already /proc/iomem parser in
tools/testing/selftests/mm/pfnmap.c that also could be lifter to vm_util

I'm fine with either approach.

My main concern is keeping the selftest decoupled from the feature
itself, so that review of the test doesn't block the feature from
landing. Would that work for you?

Sure.
 

Thanks
