From 97fb7a0a8944bd6d2c5634e1e0fa689a5c40bc22 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Sat, 3 Mar 2018 14:01:12 +0100 Subject: sched: Clean up and harmonize the coding style of the scheduler code base A good number of small style inconsistencies have accumulated in the scheduler core, so do a pass over them to harmonize all these details: - fix speling in comments, - use curly braces for multi-line statements, - remove unnecessary parentheses from integer literals, - capitalize consistently, - remove stray newlines, - add comments where necessary, - remove invalid/unnecessary comments, - align structure definitions and other data types vertically, - add missing newlines for increased readability, - fix vertical tabulation where it's misaligned, - harmonize preprocessor conditional block labeling and vertical alignment, - remove line-breaks where they uglify the code, - add newline after local variable definitions, No change in functionality: md5: 1191fa0a890cfa8132156d2959d7e9e2 built-in.o.before.asm 1191fa0a890cfa8132156d2959d7e9e2 built-in.o.after.asm Cc: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar --- kernel/sched/stats.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'kernel/sched/stats.c') diff --git a/kernel/sched/stats.c b/kernel/sched/stats.c index 940b1fa1d2ce..968c1fe3099a 100644 --- a/kernel/sched/stats.c +++ b/kernel/sched/stats.c @@ -78,8 +78,8 @@ static int show_schedstat(struct seq_file *seq, void *v) * This itererator needs some explanation. * It returns 1 for the header position. * This means 2 is cpu 0. - * In a hotplugged system some cpus, including cpu 0, may be missing so we have - * to use cpumask_* to iterate over the cpus. + * In a hotplugged system some CPUs, including cpu 0, may be missing so we have + * to use cpumask_* to iterate over the CPUs. */ static void *schedstat_start(struct seq_file *file, loff_t *offset) { @@ -99,12 +99,14 @@ static void *schedstat_start(struct seq_file *file, loff_t *offset) if (n < nr_cpu_ids) return (void *)(unsigned long)(n + 2); + return NULL; } static void *schedstat_next(struct seq_file *file, void *data, loff_t *offset) { (*offset)++; + return schedstat_start(file, offset); } @@ -134,6 +136,7 @@ static const struct file_operations proc_schedstat_operations = { static int __init proc_schedstat_init(void) { proc_create("schedstat", 0, NULL, &proc_schedstat_operations); + return 0; } subsys_initcall(proc_schedstat_init); -- cgit v1.2.3-55-g7522
