Revision ed48ece27cd3d5ee0354c32bbaec0f3e1d4715c3 authored by Tejun Heo on 18 September 2012, 19:48:43 UTC, committed by Tejun Heo on 19 September 2012, 17:13:12 UTC
The existing work_on_cpu() implementation is hugely inefficient. It creates a new kthread, execute that single function and then let the kthread die on each invocation. Now that system_wq can handle concurrent executions, there's no advantage of doing this. Reimplement work_on_cpu() using system_wq which makes it simpler and way more efficient. stable: While this isn't a fix in itself, it's needed to fix a workqueue related bug in cpufreq/powernow-k8. AFAICS, this shouldn't break other existing users.
