Subject: [PATCH v2 16/19] read-cache: write index-v5 cache-tree data
Date: Fri, 12 Jul 2013 19:27:01 +0200 [thread overview]
Message-ID: <1373650024-3001-17-git-send-email-t.gummerer@gmail.com> (raw)
In-Reply-To: <1373650024-3001-1-git-send-email-t.gummerer@gmail.com>
Write the cache-tree data for the index version 5 file format. The
in-memory cache-tree data is converted to the ondisk format, by adding
it to the directory entries, that were compiled from the cache-entries
in the step before.
