From 3d8d53554405952993bb0279ef3ebebc51740074 Mon Sep 17 00:00:00 2001 From: Dietmar Eggemann Date: Mon, 27 May 2019 07:21:12 +0100 Subject: [PATCH] sched/debug: Remove sd->*_idx range on sysctl This reverts: commit 201c373e8e48 ("sched/debug: Limit sd->*_idx range on sysctl") Load indexes (sd->*_idx) are no longer needed without rq->cpu_load[]. The range check for load indexes can be removed as well. Get rid of it before the rq->cpu_load[] since it uses CPU_LOAD_IDX_MAX. At the same time, fix the following coding style issues detected by scripts/checkpatch.pl: ERROR: space prohibited before that ',' ERROR: space prohibited before that close parenthesis ')' Signed-off-by: Dietmar Eggemann Signed-off-by: Peter Zijlstra (Intel) Acked-by: Rik van Riel Cc: Frederic Weisbecker Cc: Linus Torvalds Cc: Morten Rasmussen Cc: Patrick Bellasi Cc: Peter Zijlstra Cc: Quentin Perret Cc: Thomas Gleixner Cc: Valentin Schneider Cc: Vincent Guittot Link: https://lkml.kernel.org/r/20190527062116.11512-4-dietmar.eggemann@arm.com Signed-off-by: Ingo Molnar --- kernel/sched/debug.c | 37 ++++++++++++++----------------------- 1 file changed, 14 insertions(+), 23 deletions(-) diff --git a/kernel/sched/debug.c b/kernel/sched/debug.c index 150043e1d716..5c7b066d7de6 100644 --- a/kernel/sched/debug.c +++ b/kernel/sched/debug.c @@ -236,25 +236,16 @@ static void sd_free_ctl_entry(struct ctl_table **tablep) *tablep = NULL; } -static int min_load_idx = 0; -static int max_load_idx = CPU_LOAD_IDX_MAX-1; - static void set_table_entry(struct ctl_table *entry, const char *procname, void *data, int maxlen, - umode_t mode, proc_handler *proc_handler, - bool load_idx) + umode_t mode, proc_handler *proc_handler) { entry->procname = procname; entry->data = data; entry->maxlen = maxlen; entry->mode = mode; entry->proc_handler = proc_handler; - - if (load_idx) { - entry->extra1 = &min_load_idx; - entry->extra2 = &max_load_idx; - } } static struct ctl_table * @@ -265,19 +256,19 @@ sd_alloc_ctl_domain_table(struct sched_domain *sd) if (table == NULL) return NULL; - set_table_entry(&table[0] , "min_interval", &sd->min_interval, sizeof(long), 0644, proc_doulongvec_minmax, false); - set_table_entry(&table[1] , "max_interval", &sd->max_interval, sizeof(long), 0644, proc_doulongvec_minmax, false); - set_table_entry(&table[2] , "busy_idx", &sd->busy_idx, sizeof(int) , 0644, proc_dointvec_minmax, true ); - set_table_entry(&table[3] , "idle_idx", &sd->idle_idx, sizeof(int) , 0644, proc_dointvec_minmax, true ); - set_table_entry(&table[4] , "newidle_idx", &sd->newidle_idx, sizeof(int) , 0644, proc_dointvec_minmax, true ); - set_table_entry(&table[5] , "wake_idx", &sd->wake_idx, sizeof(int) , 0644, proc_dointvec_minmax, true ); - set_table_entry(&table[6] , "forkexec_idx", &sd->forkexec_idx, sizeof(int) , 0644, proc_dointvec_minmax, true ); - set_table_entry(&table[7] , "busy_factor", &sd->busy_factor, sizeof(int) , 0644, proc_dointvec_minmax, false); - set_table_entry(&table[8] , "imbalance_pct", &sd->imbalance_pct, sizeof(int) , 0644, proc_dointvec_minmax, false); - set_table_entry(&table[9] , "cache_nice_tries", &sd->cache_nice_tries, sizeof(int) , 0644, proc_dointvec_minmax, false); - set_table_entry(&table[10], "flags", &sd->flags, sizeof(int) , 0644, proc_dointvec_minmax, false); - set_table_entry(&table[11], "max_newidle_lb_cost", &sd->max_newidle_lb_cost, sizeof(long), 0644, proc_doulongvec_minmax, false); - set_table_entry(&table[12], "name", sd->name, CORENAME_MAX_SIZE, 0444, proc_dostring, false); + set_table_entry(&table[0], "min_interval", &sd->min_interval, sizeof(long), 0644, proc_doulongvec_minmax); + set_table_entry(&table[1], "max_interval", &sd->max_interval, sizeof(long), 0644, proc_doulongvec_minmax); + set_table_entry(&table[2], "busy_idx", &sd->busy_idx, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[3], "idle_idx", &sd->idle_idx, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[4], "newidle_idx", &sd->newidle_idx, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[5], "wake_idx", &sd->wake_idx, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[6], "forkexec_idx", &sd->forkexec_idx, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[7], "busy_factor", &sd->busy_factor, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[8], "imbalance_pct", &sd->imbalance_pct, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[9], "cache_nice_tries", &sd->cache_nice_tries, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[10], "flags", &sd->flags, sizeof(int), 0644, proc_dointvec_minmax); + set_table_entry(&table[11], "max_newidle_lb_cost", &sd->max_newidle_lb_cost, sizeof(long), 0644, proc_doulongvec_minmax); + set_table_entry(&table[12], "name", sd->name, CORENAME_MAX_SIZE, 0444, proc_dostring); /* &table[13] is terminator */ return table;
