From 1dc01abad6544cb9d884071b626b706e37aa9601 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Thu, 13 Jan 2022 16:53:57 +0100 Subject: [PATCH] cpumask: Always inline helpers which use bit manipulation functions Former are always inlined so do that for the latter too, for consistency. Size impact is a whopping 5 bytes increase! :-) text data bss dec hex filename 22350551 8213184 1917164 32480899 1ef9e83 vmlinux.x86-64.defconfig.before 22350556 8213152 1917164 32480872 1ef9e68 vmlinux.x86-64.defconfig.after Signed-off-by: Borislav Petkov Signed-off-by: Peter Zijlstra (Intel) Acked-by: Marco Elver Link: https://lore.kernel.org/r/20220113155357.4706-3-bp@alien8.de --- include/linux/cpumask.h | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/include/linux/cpumask.h b/include/linux/cpumask.h index 64dae70..6b06c69 100644 --- a/include/linux/cpumask.h +++ b/include/linux/cpumask.h @@ -341,12 +341,12 @@ extern int cpumask_next_wrap(int n, const struct cpumask *mask, int start, bool * @cpu: cpu number (< nr_cpu_ids) * @dstp: the cpumask pointer */ -static inline void cpumask_set_cpu(unsigned int cpu, struct cpumask *dstp) +static __always_inline void cpumask_set_cpu(unsigned int cpu, struct cpumask *dstp) { set_bit(cpumask_check(cpu), cpumask_bits(dstp)); } -static inline void __cpumask_set_cpu(unsigned int cpu, struct cpumask *dstp) +static __always_inline void __cpumask_set_cpu(unsigned int cpu, struct cpumask *dstp) { __set_bit(cpumask_check(cpu), cpumask_bits(dstp)); } @@ -357,12 +357,12 @@ static inline void __cpumask_set_cpu(unsigned int cpu, struct cpumask *dstp) * @cpu: cpu number (< nr_cpu_ids) * @dstp: the cpumask pointer */ -static inline void cpumask_clear_cpu(int cpu, struct cpumask *dstp) +static __always_inline void cpumask_clear_cpu(int cpu, struct cpumask *dstp) { clear_bit(cpumask_check(cpu), cpumask_bits(dstp)); } -static inline void __cpumask_clear_cpu(int cpu, struct cpumask *dstp) +static __always_inline void __cpumask_clear_cpu(int cpu, struct cpumask *dstp) { __clear_bit(cpumask_check(cpu), cpumask_bits(dstp)); } @@ -374,7 +374,7 @@ static inline void __cpumask_clear_cpu(int cpu, struct cpumask *dstp) * * Returns 1 if @cpu is set in @cpumask, else returns 0 */ -static inline int cpumask_test_cpu(int cpu, const struct cpumask *cpumask) +static __always_inline int cpumask_test_cpu(int cpu, const struct cpumask *cpumask) { return test_bit(cpumask_check(cpu), cpumask_bits((cpumask))); } @@ -388,7 +388,7 @@ static inline int cpumask_test_cpu(int cpu, const struct cpumask *cpumask) * * test_and_set_bit wrapper for cpumasks. */ -static inline int cpumask_test_and_set_cpu(int cpu, struct cpumask *cpumask) +static __always_inline int cpumask_test_and_set_cpu(int cpu, struct cpumask *cpumask) { return test_and_set_bit(cpumask_check(cpu), cpumask_bits(cpumask)); } @@ -402,7 +402,7 @@ static inline int cpumask_test_and_set_cpu(int cpu, struct cpumask *cpumask) * * test_and_clear_bit wrapper for cpumasks. */ -static inline int cpumask_test_and_clear_cpu(int cpu, struct cpumask *cpumask) +static __always_inline int cpumask_test_and_clear_cpu(int cpu, struct cpumask *cpumask) { return test_and_clear_bit(cpumask_check(cpu), cpumask_bits(cpumask)); } -- 2.7.4
