Description
The problem is that finish_ctx does not really work on snapdirs (snaptrimmer does not use finish_ctx, and make_writeable handles snapdir specially). The repop does not get processed correctly for deep scrubs on snapdir objects. However, do we really want to record the digest on a snapdir object?
