From a18f7ffc8c9a5a9c72b5aa064e995ff3720be5df Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Fri, 2 Nov 2018 15:47:53 -0700 Subject: [PATCH] include/linux/notifier.h: SRCU: fix ctags 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.
