From 89073af905c478c4dcd8f2cac625f01039700aad Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Wed, 13 Feb 2019 18:40:24 +0800 Subject: [PATCH] include/linux/notifier.h: SRCU: fix ctags mainline inclusion from mainline-4.20-rc1 commit 94e297c50b529f5d01cfd1dbc808d61e95180ab7 category: bugfix bugzilla: 5542 CVE: NA --------------------------- ctags indexing ("make tags" command) throws this warning: ctags: Warning: include/linux/notifier.h:125: null expansion of name pattern "\1" This is the result of DEFINE_PER_CPU() macro expansion. Fix that by getting rid of line break. Similar fix was already done in commit 25528213fe9f ("tags: Fix DEFINE_PER_CPU expansions"), but this one probably wasn't noticed.
