From f276b50c3a5b01c1b6636adb3e4eba67d187d218 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 11 Jun 2017 15:51:56 -0700 Subject: [PATCH] compiler, clang: properly override 'inline' for clang commit 6d53cefb18e4646fb4bf62ccb6098fb3808486df upstream. Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused static inline functions") just caused more warnings due to re-defining the 'inline' macro. So undef it before re-defining it, and also add the 'notrace' attribute like the gcc version that this is overriding does. Maybe this makes clang happier.
