Subject: [PATCH v2 13/42] fsck: convert static functions to struct object_id
Date: Wed, 2 May 2018 00:25:41 +0000 [thread overview]
Message-ID: <20180502002610.915892-14-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20180502002610.915892-1-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.
