[PATCH 13/23] fsck: only provide oid/type in fsck_error callback

From
Jeff King <peff@peff.net>
Date
Oct 18, 2019, 04:58 UTC
Message-ID
<20191018045840.GM17879@sigill.intra.peff.net>
In-Reply-To
<20191018044103.GA17625@sigill.intra.peff.net>

None of the callbacks actually care about having a "struct object"; they're happy with just the oid and type information. So let's give ourselves more flexibility to avoid having a "struct object" by just passing the broken-down fields.

Note that the callback already takes a "type" field for the fsck message type. We'll rename that to "msg_type" (and use "object_type" for the object type) to make the distinction explicit.
