Subject: [PATCH 03/17] drbd: centralize printk reporting of new size into drbd_set_my_capacity()
Date:   Thu, 20 Dec 2018 17:23:30 +0100
Message-Id: <20181220162344.8430-4-lars.ellenberg@linbit.com>
In-Reply-To: <20181220162344.8430-1-lars.ellenberg@linbit.com>
References: <20181220162344.8430-1-lars.ellenberg@linbit.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Previously, some implicit resizes that happend during handshake
have not been reported as prominently as explicit resize.
