From f9b8d11b312f8caaa9dfcf15fc7ab60d9167a6d0 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 [ Upstream commit 4613012db1d911f80897f9446a49de817b2c4c47 ] 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.
