Subject: [PATCH 0/5] Cpufreq fixes related to cpu hotplug/sysfs-writes
Date: Sat, 07 Sep 2013 01:22:44 +0530 [thread overview]
Message-ID: <20130906195206.26919.20884.stgit@srivatsabhat.in.ibm.com> (raw)
Hi,
This patchset solves the cpufreq synchronization problems related to CPU
hotplug and writes to cpufreq sysfs files. The problem was reported and
described by Stephen Boyd here:
https://lkml.org/lkml/2013/8/27/643
https://lkml.org/lkml/2013/8/30/597
All the patches apply on Rafael's bleeding-edge branch on linux-pm git
tree[1].
[1]. git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git bleeding-edge
Srivatsa S. Bhat (5):
cpufreq: Split __cpufreq_remove_dev() into 2 parts (kobj cleanup & the rest)
cpufreq: Invoke __cpufreq_remove_dev_finish() after releasing cpu_hotplug.lock
cpufreq: Synchronize the cpufreq store_*() routines with CPU hotplug
cpufreq: Remove temporary fix for race between CPU hotplug and sysfs-writes
cpufreq: Use signed type for 'ret' variable, to store negative error values
