In commit 7ee681b25284 ("workqueue: Convert to state machine callbacks"),
three new function definitions were added: ‘workqueue_prepare_cpu’,
‘workqueue_online_cpu’ and ‘workqueue_offline_cpu’.Move these function definitions within a CONFIG_SMP block since they are not used outside of it. This will match function declarations in header <include/linux/workqueue.h>, and silence the following gcc warning (W=1): kernel/workqueue.c:4743:5: warning: no previous prototype for ‘workqueue_prepare_cpu’ [-Wmissing-prototypes] kernel/workqueue.c:4756:5: warning: no previous prototype for ‘workqueue_online_cpu’ [-Wmissing-prototypes] kernel/workqueue.c:4783:5: warning: no previous prototype for ‘workqueue_offline_cpu’ [-Wmissing-prototypes] Signed-off-by: Mathieu Malaterre <[email protected]> --- kernel/workqueue.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/kernel/workqueue.c b/kernel/workqueue.c index ca7959be8aaa..c1544225c696 100644 --- a/kernel/workqueue.c +++ b/kernel/workqueue.c @@ -4579,6 +4579,8 @@ void show_workqueue_state(void) rcu_read_unlock_sched(); } +#ifdef CONFIG_SMP + /* * CPU hotplug. * @@ -4799,8 +4801,6 @@ int workqueue_offline_cpu(unsigned int cpu) return 0; } -#ifdef CONFIG_SMP - struct work_for_cpu { struct work_struct work; long (*fn)(void *); -- 2.11.0
