Subject: [PATCH -next] percpu: make symbol 'pcpu_free_slot' static
Date: Fri, 14 May 2021 06:39:52 +0000 [thread overview]
Message-ID: <20210514063952.3240527-1-weiyongjun1@huawei.com> (raw)
The sparse tool complains as follows:
mm/percpu.c:138:5: warning:
symbol 'pcpu_free_slot' was not declared. Should it be static?
This symbol is not used outside of percpu.c, so marks it static.
