commit 6f72df247d4895810c1ab8a6322487e139093ffe Author: Vladimir Serbinenko phcoder@gmail.com Date: Sun Jan 12 14:12:15 2014 +0100
CBFS: use cbfs_get_file_content whenever possible rather than cbfs_get_file
Number one reason to use cbfs_get_file was to get file length. With prvious patch no more need for this.
