From: Palmer Dabbelt <palmer@xxxxxxxxxxxx> The variable "one_thousand" is only used under CONFIG_PERF_EVENTS=y, but is unconditionally defined. This can fire a warning. Signed-off-by: Palmer Dabbelt <palmer@xxxxxxxxxxxx> --- I went with an #ifdef instead of a __maybe_unused because that's what the other code is using, and I left the one_thousand in order despite that requiring another #ifdef. --- kernel/sysctl.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/kernel/sysctl.c b/kernel/sysctl.c index ef77be575d87..81a6f2d47f77 100644 --- a/kernel/sysctl.c +++ b/kernel/sysctl.c @@ -122,7 +122,9 @@ static unsigned long one_ul = 1; static unsigned long long_max = LONG_MAX; static int one_hundred = 100; static int two_hundred = 200; +#ifdef CONFIG_PERF_EVENTS static int one_thousand = 1000; +#endif static int three_thousand = 3000; #ifdef CONFIG_PRINTK static int ten_thousand = 10000; -- 2.32.0
