From 203583990cb675aeddff6d7623f68268068c078c Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 21 Aug 2018 21:55:45 -0700 Subject: [PATCH] linux/compiler.h: don't use bool Appararently, it's possible to have a non-trivial TU include a few headers, including linux/build_bug.h, without ending up with linux/types.h. So the 0day bot sent me config: um-x86_64_defconfig (attached as .config) >> include/linux/compiler.h:316:3: error: unknown type name 'bool'; did you mean '_Bool'? bool __cond = !(condition); \ for something I'm working on. Rather than contributing to the #include madness and including linux/types.h from compiler.h, just use int.
