Subject: [PATCH 7/7] btrfs: remove orig_bytes from reserve_ticket
Date: Fri,  9 Aug 2019 09:33:27 -0400
Message-ID: <20190809133327.26509-8-josef@toxicpanda.com> (raw)
In-Reply-To: <20190809133327.26509-1-josef@toxicpanda.com>

Now that we do not do partial filling of tickets simply remove
orig_bytes, it is no longer needed.
