Cover letter [RFC PATCH 0/3] Refcount Based Cpu Hotplug V3
Hi,
This is Try #3 for the Refcount + Waitqueue based implementation for cpu-hotplug locking. The earlier versions can be found at
http://lkml.org/lkml/2007/10/24/36
and
http://lkml.org/lkml/2007/10/16/118.
This version drops the patch 4 from the earlier series, which was basically removing the CPU_DEAD and CPU_UP_CANCELLED event handling in the workqueue subsystem. This was based on Oleg Nestertov's comments since the problem which the patch was attempting to solve was more complicated and needs to be looked into seperately.
The patch series is against v2.6.24-rc2 and has survived overnight kern_bench + cpu-offline-online tests on
- 8 way x86,
- 8 way x86_64,
- 128 way ppc64 boxes.
The patch series has gone through many iterations
and looks to have matured in the process.
Andrew, could you please consider it for the next -mm release if there are no objections ?
Thanks and Regards
gautham.
