+                        with each line containing a target.

We have OF nodes in sysfs now. Would it be more useful if we created
links to the target nodes instead of having a list of names?

Probably, this interface is merely informational; things get complicated by
the fact that there can be more than one target in each overlay.

Right, you would need 'targetN' or perhaps '<node name>' (with a '.N'
for duplicates) as the link names.

If it is informational, then perhaps debugfs should be used instead?

What else if anything do you envision adding here?
