From 50a3499ab853acd5ae5056231a576637af1bed8d Mon Sep 17 00:00:00 2001 From: Jon Maloy Date: Tue, 16 Mar 2021 22:06:11 -0400 Subject: tipc: simplify signature of tipc_namtbl_publish() Using the new address structure tipc_uaddr, we simplify the signature of function tipc_sk_publish() and tipc_namtbl_publish() so that fewer parameters need to be passed around.
