From 9c37510b8ff2821ae4574858a6d4e83949c98a20 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Fri, 19 Apr 2013 10:33:59 +0900 Subject: [PATCH] ipvs: Use min3() in ip_vs_dbg_callid() There are two motivations for this: 1. It improves readability to my eyes 2. Using nested min() calls results in a shadowed _min1 variable, which is a bit untidy. Sparse complained about this. I have also replaced (size_t)64 with a variable of type size_t and value 64. This also improves readability to my eyes.
