| |
Hello everyone,
A couple of months ago Zdenek Kabelac had reported a Circular locking dependency in resume, which was related to the locking dependency between the cpufreq and CPU-Hotplug subsystems.
http://lkml.org/lkml/2008/2/26/479
This patchset aggregates the various patches that have been posted in the recent past, to solve this problem.
There are a few more TODO items in CPU-Hotplug , unrelated to this problem, that cropped up in the various discussions. They will be posted in a seperate thread.
The patchstack has been lightly tested on a 4-way x86 machine with CPU-Hotplug running in parallel with kernbench and changing cpufreq governors simultaneously.
Awaiting your feedback, gautham
