From 489111e5c25b93be80340c3113d71903d7c82136 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 24 Oct 2016 14:40:03 +0200 Subject: genetlink: statically initialize families Instead of providing macros/inline functions to initialize the families, make all users initialize them statically and get rid of the macros. This reduces the kernel code size by about 1.6k on x86-64 (with allyesconfig). Signed-off-by: Johannes Berg Signed-off-by: David S.
