Subject: [PATCH 2/9] Btrfs-progs: search subvolumes with proper objectid
Date: Fri, 3 Aug 2012 17:48:51 +0800 [thread overview]
Message-ID: <1343987338-10612-4-git-send-email-Anand.Jain@oracle.com> (raw)
In-Reply-To: <1343987338-10612-1-git-send-email-Anand.Jain@oracle.com>
From: Liu Bo <liubo2009@cn.fujitsu.com>
Btrfs's subvolume/snapshot is limited to
[BTRFS_FIRST_FREE_OBJECTID, BTRFS_LAST_FREE_OBJECTID], so just apply the range.
