From e92b848cb6a77172d2fbd2bda39a32e371d40eea Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 6 May 2017 22:10:06 +0000 Subject: shallow: convert shallow registration functions to object_id Convert register_shallow and unregister_shallow to take struct object_id. register_shallow is a caller of lookup_commit, which we will convert later. It doesn't make sense for the registration and unregistration functions to have incompatible interfaces, so convert them both.
