Subject: [PATCH 13/41] fsck: convert static functions to struct object_id
Date: Mon, 23 Apr 2018 23:39:23 +0000	[thread overview]
Message-ID: <20180423233951.276447-14-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20180423233951.276447-1-sandals@crustytoothpaste.net>

Convert two static functions to use struct object_id and parse_oid_hex,
instead of relying on harcoded 20 and 40-based constants.
