sched/topology: Rename sched_group_cpus()
There's a discrepancy in naming between the sched_domain and sched_group cpumask accessor. Since we're doing changes, fix it. $ git grep sched_group_cpus | wc -l 28 $ git grep sched_domain_span | wc -l 38 Suggests changing sched_group_cpus() into sched_group_span(): for i in `git grep -l sched_group_cpus` do sed -ie 's/sched_group_cpus/sched_group_span/g' $i done Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
