Subject: [PATCH v2 0/4] Unify CPU hotplug lock interface
Date: Thu, 29 Aug 2013 18:22:05 -0600 [thread overview]
Message-ID: <1377822129-4143-1-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().
v2:
- Rebased to the pm tree, bleeding-edge.
- Changed patch 2/4 to use lock_device_hotplug_sysfs().
