Subject: [PATCH v4 12/12] pack-bitmap: don't rely on bitmap_git->reuse_objects
Date: Wed, 18 Dec 2019 12:25:47 +0100	[thread overview]
Message-ID: <20191218112547.4974-13-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20191218112547.4974-1-chriscool@tuxfamily.org>

From: Jeff King <peff@peff.net>

We no longer compute bitmap_git->reuse_objects, so we
cannot rely on it anymore to terminate the loop early;
we have to iterate to the end.
