Subject: [PATCH] Btrfs: remove dead code block
Date: Thu, 13 Oct 2011 00:21:37 +0300	[thread overview]
Message-ID: <1318454497-25244-1-git-send-email-idryomov@gmail.com> (raw)

This has been effectively unreachable for years, btrfs_read_dev_super()
implements this check earlier in the mount sequence.
