Subject: [PATCH 1/6] btrfs-progs: Add support for freespace tree in btrfs_read_fs_root
Date: Fri, 15 Jun 2018 14:05:57 +0300 [thread overview]
Message-ID: <1529060762-4372-2-git-send-email-nborisov@suse.com> (raw)
In-Reply-To: <1529060762-4372-1-git-send-email-nborisov@suse.com>
For completeness sake add code to btrfs_read_fs_root so that it can
handle the freespace tree.
