From fb49d19ed9da82f26d3e43122ddaf8bf31a122bd Mon Sep 17 00:00:00 2001 From: Mathieu Malaterre Date: Wed, 16 May 2018 21:53:47 +0200 Subject: [PATCH] sched/debug: Move the print_rt_rq() and print_dl_rq() declarations to kernel/sched/sched.h MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit f6a3463063f42d9fb2c78f386437a822e0ad1792 ] In the following commit: 6b55c9654fcc ("sched/debug: Move print_cfs_rq() declaration to kernel/sched/sched.h") the print_cfs_rq() prototype was added to , right next to the prototypes for print_cfs_stats(), print_rt_stats() and print_dl_stats(). Finish this previous commit and also move related prototypes for print_rt_rq() and print_dl_rq(). Remove existing extern declarations now that they not needed anymore. Silences the following GCC warning, triggered by W=1: kernel/sched/debug.c:573:6: warning: no previous prototype for ‘print_rt_rq’ [-Wmissing-prototypes] kernel/sched/debug.c:603:6: warning: no previous prototype for ‘print_dl_rq’ [-Wmissing-prototypes] Signed-off-by: Mathieu Malaterre Acked-by: Peter Zijlstra Cc: Linus Torvalds Cc: Srikar Dronamraju Cc: Thomas Gleixner Link: http://lkml.kernel.org/r/20180516195348.30426-1-malat@debian.org Signed-off-by: Ingo Molnar Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- kernel/sched/deadline.c | 2 -- kernel/sched/rt.c | 2 -- kernel/sched/sched.h | 5 +++-- 3 files changed, 3 insertions(+), 6 deletions(-) diff --git a/kernel/sched/deadline.c b/kernel/sched/deadline.c index 4ae5c1e..1f4047c 100644 --- a/kernel/sched/deadline.c +++ b/kernel/sched/deadline.c @@ -2655,8 +2655,6 @@ bool dl_cpu_busy(unsigned int cpu) #endif #ifdef CONFIG_SCHED_DEBUG -extern void print_dl_rq(struct seq_file *m, int cpu, struct dl_rq *dl_rq); - void print_dl_stats(struct seq_file *m, int cpu) { print_dl_rq(m, cpu, &cpu_rq(cpu)->dl); diff --git a/kernel/sched/rt.c b/kernel/sched/rt.c index 113eaeb..bba2217 100644 --- a/kernel/sched/rt.c +++ b/kernel/sched/rt.c @@ -2689,8 +2689,6 @@ int sched_rr_handler(struct ctl_table *table, int write, } #ifdef CONFIG_SCHED_DEBUG -extern void print_rt_rq(struct seq_file *m, int cpu, struct rt_rq *rt_rq); - void print_rt_stats(struct seq_file *m, int cpu) { rt_rq_iter_t iter; diff --git a/kernel/sched/sched.h b/kernel/sched/sched.h index 307c35d3..b293761 100644 --- a/kernel/sched/sched.h +++ b/kernel/sched/sched.h @@ -1969,8 +1969,9 @@ extern bool sched_debug_enabled; extern void print_cfs_stats(struct seq_file *m, int cpu); extern void print_rt_stats(struct seq_file *m, int cpu); extern void print_dl_stats(struct seq_file *m, int cpu); -extern void -print_cfs_rq(struct seq_file *m, int cpu, struct cfs_rq *cfs_rq); +extern void print_cfs_rq(struct seq_file *m, int cpu, struct cfs_rq *cfs_rq); +extern void print_rt_rq(struct seq_file *m, int cpu, struct rt_rq *rt_rq); +extern void print_dl_rq(struct seq_file *m, int cpu, struct dl_rq *dl_rq); #ifdef CONFIG_NUMA_BALANCING extern void show_numa_stats(struct task_struct *p, struct seq_file *m); -- 2.7.4
