Subject: [PATCHv2 for-next 10/12] RDMA/rtrs-srv: kill rtrs_srv_change_state_get_old
Date: Fri, 23 Oct 2020 09:43:51 +0200
Message-ID: <20201023074353.21946-11-jinpu.wang@cloud.ionos.com> (raw)
In-Reply-To: <20201023074353.21946-1-jinpu.wang@cloud.ionos.com>

From: Guoqing Jiang <guoqing.jiang@cloud.ionos.com>

This function isn't needed since no caller checks the old_state of sess.
