From 26549dab8a4676ce549cb20bf384daf458a9ea24 Mon Sep 17 00:00:00 2001 From: Li Zetao Date: Thu, 22 Aug 2024 21:39:06 +0800 Subject: [PATCH] ipv6: mcast: use min() to simplify the code When coping sockaddr in ip6_mc_msfget(), the time of copies depends on the minimum value between sl_count and gf_numsrc. Using min() here is very semantic.
