Re: [PATCH 09/16] prune: factor out loose-object directory traversal

Jeff King [off-list ref] writes:

Prune has to walk $GIT_DIR/objects/?? in order to find the
set of loose objects to prune. Other parts of the code
(e.g., count-objects) want to do the same. Let's factor it
out into a reusable for_each-style function.

Doesn't fsck also look at these as well?  I recall that we also have
a "sort by inum" trick employed there.  Would it also be applicable
to these two callers?
