Subject: [PATCH v2 for-next 1/6] RDMA/rtrs-clt: During add_path change for_new_clt according to path_num
Date: Fri, 6 Aug 2021 13:21:07 +0200 [thread overview]
Message-ID: <20210806112112.124313-2-haris.iqbal@ionos.com> (raw)
In-Reply-To: <20210806112112.124313-1-haris.iqbal@ionos.com>
When all the paths are removed for a session, the addition of the first
path is like a new session for the storage server.
Hence, for_new_clt has to be set to 1.
