From 4613012db1d911f80897f9446a49de817b2c4c47 Mon Sep 17 00:00:00 2001 From: Aaron Conole Date: Sat, 26 Sep 2015 18:50:42 -0400 Subject: [PATCH] af_unix: Convert the unix_sk macro to an inline function for type safety As suggested by Eric Dumazet this change replaces the #define with a static inline function to enjoy complaints by the compiler when misusing the API.
