Could you guys cooperate and organize a single fix series?  That'd be
nicer at merge.

Also, about the unit test: I'm not much against kunit, but my gut
feeling is that selftest would be more flexible (and less changes in
the core code itself).  If that's feasible, let's go in that way.
Otherwise we can take the kunit change.  But maybe it's cleaner to
move the test code into another file.


thanks,

Takashi
