From 49aadcf1b6f4240751921dad52e86c760d70a5f1 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Wed, 27 Jul 2016 23:11:47 -0400 Subject: [PATCH] extable.h: add stddef.h so "NULL" definition is not implicit While not an issue now, eventually we will have independent users of the extable.h file and we will stop sourcing it via module.h header. In testing that pending work, with very sparse builds, characteristic of an "allnoconfig" on various architectures, we can sometimes hit an instance where the very basic standard definitions aren't present, resulting in: include/linux/extable.h:26:9: error: 'NULL' undeclared (first use in this function) To be clear, this isn't a regression, since currently extable.h is only used by module.h -- however, we will need this addition present before we start migrating exception table users off module.h and onto extable.h during the next release cycle.
