Subject: [PATCH 03/18] fsck: support referenced promisor objects
Date: Fri, 29 Sep 2017 13:11:39 -0700
Message-ID: <5e5806e020a639560bca397d77045cc5286c1655.1506714999.git.jonathantanmy@google.com> (raw)
In-Reply-To: <cover.1506714999.git.jonathantanmy@google.com>

Teach fsck to not treat missing promisor objects indirectly pointed to
by refs as an error when extensions.partialclone is set.
