| |
The following series implements the infrastructure for parking and unparking kernel threads to avoid the full teardown and fork on cpu hotplug operations along with management infrastructure for hotplug and users.
Changes since V1:
- Addressed the review comments - Fixed a missing state update in parkme (reported by Paul) - Simplified rcu_yield() - Added Pauls RCU conversion
Full diffstat below. Due to the RCU cleanup we now remove more code than we add. :)
Thanks,
