Subject: [PATCH v1 0/3] cpufreq: Locking-related changes in cpufreq_offline() and cpufreq_remove_dev()
Date: Wed, 11 May 2022 17:46:41 +0200	[thread overview]
Message-ID: <5585781.DvuYhMxLoT@kreacher> (raw)

Hi,

This series is based on the observation that the policy rwsem is used (or rather not
used) inconsistently in cpufreq_remove_dev() (in summary, it does things without
holding the policy rwsem that are done under that rwsem elsewhere).

The first two patches are preparatory (but patch [1/3] is a good enough improvement
by itself IMO) and patch [3/3] makes the essential change.

Please refer to the patch changelogs for details.

Thanks!
