Subject: [PATCH v2] kernel/SRCU: Fix ctags
Date: Tue, 30 Oct 2018 20:28:08 +0000
Message-ID: <20181030202808.28027-1-semen.protsenko@linaro.org> (raw)
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.
Fixes: 9c80172b902d ("kernel/SRCU: provide a static initializer")
