[PATCH v3 04/36] cache-tree: convert remnants to struct object_id

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Mar 12, 2018, 02:27 UTC
Message-ID
<20180312022756.483934-5-sandals@crustytoothpaste.net>
In-Reply-To
<20180312022756.483934-1-sandals@crustytoothpaste.net>

Convert the remaining portions of cache-tree.c to use struct object_id. Convert several instances of 20 to use the_hash_algo instead.
