Hi Andrew, > remove-hotplug-cpu-crap-from-cpufreq.patch > > Sent to cpufreq maintainer
I suspect that Davej posted this patch because he was getting lockdep warnings-reports from people complaining of ondemand-governor performing spurious unlock_cpu_hotplug. That problem has been fixed in the mainline by the commit http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=4b96b1a10cb00c867103b21f0f2a6c91b705db11 If there are any other issues with cpufreq-cpuhotplug in the mainline, I'm more than willing to help out fix them. As of now, I cannot seem to spot anything serious in the mainline as such. Hence, merging this isn't an immediate need IMHO. > hotplug-cpu-clean-up-hotcpu_notifier-use.patch > hotplug-cpu-clean-up-hotcpu_notifier-use-vs-gregkh-driver-cpu-topology-consider-sysfs_create_group-return-value.patch > > extend-notifier_call_chain-to-count-nr_calls-made.patch > extend-notifier_call_chain-to-count-nr_calls-made-fixes.patch > extend-notifier_call_chain-to-count-nr_calls-made-fixes-2.patch > define-and-use-new-eventscpu_lock_acquire-and-cpu_lock_release.patch > define-and-use-new-eventscpu_lock_acquire-and-cpu_lock_release-fix.patch > eliminate-lock_cpu_hotplug-in-kernel-schedc.patch > eliminate-lock_cpu_hotplug-in-kernel-schedc-fix.patch > handle-cpu_lock_acquire-and-cpu_lock_release-in-workqueue_cpu_callback.patch > > Shall merge. > Merging this would still give the circular-locking dependency warnings which I posted the other day. Unless we have a clean way to get cpu-hotplug-protection for cpufreq, I don't see a point in merging this stuff. Cpufreq hotplug-interactions can be sorted out. I have a few patches which I need to test out before posting them. Other than that, there are issues regarding the workqueue-hotplug-"locking" which needs to be addressed, probably in a seperate thread. So could you please reconsider this decision to merge the hotplug-locking rework, and let it stabilize in -mm for sometime ?
