If anyone has any objections, please let me know. ------------------ From: Aaron Conole [ 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.
