Subject: [RFC patch V2 0/7] Per cpu thread hotplug infrastructure
Date: Fri, 15 Jun 2012 14:13:19 -0000 [thread overview]
Message-ID: <20120615140217.933711648@linutronix.de> (raw)
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,
tglx
