| H A D | cpufreq.h | diff 5a01f2e8f3ac134e24144d74bb48a60236f7024d Mon Feb 05 18:12:44 CST 2007 Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> [CPUFREQ] Rewrite lock in cpufreq to eliminate cpufreq/hotplug related issues
Yet another attempt to resolve cpufreq and hotplug locking issues.
Patchset has 3 patches:
* Rewrite the lock infrastructure of cpufreq using a per cpu rwsem.
* Minor restructuring of work callback in ondemand driver.
* Use the new cpufreq rwsem infrastructure in ondemand work.
This patch:
Convert policy->lock to rwsem and move it to per_cpu area.
This rwsem will protect against both changing/accessing policy
related parameters and CPU hot plug/unplug.
