Subject: [PATCH 07/13] Btrfs-progs: make printing subvol extensible to newer layouts
Date: Fri,  1 Feb 2013 15:56:26 +0800	[thread overview]
Message-ID: <1359705392-7485-8-git-send-email-anand.jain@oracle.com> (raw)
In-Reply-To: <1359705392-7485-1-git-send-email-anand.jain@oracle.com>

Currently you can print subvol in a list or table format.
This patch will provide a way to extend this to other formats
like the upcoming raw format.
