Subject: kernel/workqueue.c: fix DEFINE_PER_CPU_SHARED_ALIGNED expansion
Date: Wed, 11 Sep 2024 13:07:28 +0800
Make tags always produces below annoying warnings:
ctags: Warning: kernel/workqueue.c:470: null expansion of name pattern "\1"
ctags: Warning: kernel/workqueue.c:474: null expansion of name pattern "\1"
ctags: Warning: kernel/workqueue.c:478: null expansion of name pattern "\1"
In commit 25528213fe9f ("tags: Fix DEFINE_PER_CPU expansions"), codes in
places have been adjusted including cpu_worker_pools definition. I noticed
in commit 4cb1ef64609f ("workqueue: Implement BH workqueues to eventually
replace tasklets"), cpu_worker_pools definition was unfolded back. Not
sure if it was intentionally done or ignored carelessly.
Makes change to mute them specifically.
