[PATCH 12/17] delta-islands: convert island_marks khash to use oids

From
Jeff King <peff@peff.net>
Date
Jun 20, 2019, 07:41 UTC
Message-ID
<20190620074131.GL3713@sigill.intra.peff.net>
In-Reply-To
<20190620073952.GA1539@sigill.intra.peff.net>

All of the users of this map have an actual "struct object_id" rather than a bare sha1. Let's use the more descriptive type (and get one step closer to dropping khash_sha1 entirely).
