Hmm, it looks somewhat bogus - it is using log links long time after it
has been invalidated completely.
It has fallback sollution that just looks backward when links are
broken.  Would be acceptable to simply drop the log link part?

Alternatively df.c would probably do what sh wants, but I think it will
get to the busy path quite often anyway and in the case was not problem
so far I would guess that it won't be.
