Subject: [PATCH 0/4] Unify CPU hotplug lock interface
Date: Sat, 17 Aug 2013 13:46:55 -0600 [thread overview]
Message-ID: <1376768819-28975-1-git-send-email-toshi.kani@hp.com> (raw)
lock_device_hotplug() was recently introduced to serialize CPU & Memory
online/offline and hotplug operations, along with sysfs online interface
restructure (commit 4f3549d7). With this new locking scheme,
cpu_hotplug_driver_lock() is redundant and is no longer necessary.
This patchset makes sure that lock_device_hotplug() covers all CPU online/
offline interfaces, and then removes cpu_hotplug_driver_lock().
The patchset is based on Linus's tree, 3.11.0-rc5.
