[PATCH v2 06/10] pack-bitmap: allow passing payloads to `show_reachable_fn()`

From
Patrick Steinhardt <ps@pks.im>
Date
Mar 27, 2025, 09:44 UTC
Message-ID
<20250327-pks-cat-file-object-type-filter-v2-6-4bbc7085d7c5@pks.im>
In-Reply-To
<20250327-pks-cat-file-object-type-filter-v2-0-4bbc7085d7c5@pks.im>

The `show_reachable_fn` callback is used by a couple of functions to present reachable objects to the caller. The function does not provide a way for the caller to pass a payload though, which is functionality that we'll require in a subsequent commit.

Change the callback type to accept a payload and adapt all callsites accordingly.
