Subject: [PATCH 30/33] tipc: call tsk_set_importance from tipc_topsrv_create_listener
Date: Wed, 20 May 2020 21:55:06 +0200 [thread overview]
Message-ID: <20200520195509.2215098-31-hch@lst.de> (raw)
In-Reply-To: <20200520195509.2215098-1-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
Signed-off-by: Christoph Hellwig <hch@lst.de>
