I suppose the kill_litter_super()->kill_anon_super() should probably

It very much is related - anything persistent left at ->kill_sb() time
will be taken out by generic_shutdown_super().  If all pinned objects
in there are marked persistent, kill_litter_super() becomes equivalent
to kill_anon_super() for that fs.

Sure, we can switch to kill_anon_super() in a separate later patch,
but conversion to d_make_persistent() will be a hard prereq for it.
No point splitting that one line, IMO...
