Subject: [PATCH 19/31] btrfs: struct btrfsic_state->root should be an fs_info
Date: Fri, 24 Jun 2016 18:15:12 -0400	[thread overview]
Message-ID: <1466806524-27508-20-git-send-email-jeffm@suse.com> (raw)
In-Reply-To: <1466806524-27508-1-git-send-email-jeffm@suse.com>

From: Jeff Mahoney <jeffm@suse.com>

The root member is never used except for obtaining an fs_info pointer.
