Subject: [PATCH v2 0/2] sched: fix nr_busy_cpus
Date: Tue, 29 Jan 2013 11:38:58 +0100 [thread overview]
Message-ID: <1359455940-1710-1-git-send-email-vincent.guittot@linaro.org> (raw)
The nr_busy_cpus field of the sched_group_power is sometime different from 0
whereas the platform is fully idle. This serie fixes 3 use cases:
- when some CPUs enter idle state while booting all CPUs
- when a CPU is unplug and/or replug
Change since V1:
- remove the patch for SCHED softirq on an idle core use case as it was
a side effect of the other use cases.

sched: fix init NOHZ_IDLE flag
sched: fix update NOHZ_IDLE flag
