Subject: [PATCH 30/33] tipc: call tsk_set_importance from tipc_topsrv_create_listener
Date: Wed, 13 May 2020 08:26:45 +0200
Message-ID: <20200513062649.2100053-31-hch@lst.de> (raw)
In-Reply-To: <20200513062649.2100053-1-hch@lst.de>

Avoid using kernel_setsockopt for the TIPC_IMPORTANCE option when we can
just use the internal helper.  The only change needed is to pass a struct
sock instead of tipc_sock, which is private to socket.c
