From f25a9b8515a40cdd8cea9d38176d78266f5f941e Mon Sep 17 00:00:00 2001 From: Andrea Claudi Date: Sat, 16 Feb 2019 16:39:53 +0100 Subject: [PATCH] ipvs: change some data types from int to bool Change the data type of the following variables from int to bool across ipvs code: - found - loop - need_full_dest - need_full_svc - payload_csum Also change the following functions to use bool full_entry param instead of int: - ip_vs_genl_parse_dest() - ip_vs_genl_parse_service() This patch does not change any functionality but makes the source code slightly easier to read.
