I suggest to improve also this commit message.

* Please reduce uncertainty.

* An imperative wording is probably preferred, isn't it?
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=152036d1379ffd6985262743dcf6b0f9c75f83a4#n151

* Will it be more appropriate to refer to the transformation “Reduce the lock scope”?

* Would you like to add the tag “Fixes” to the change description?

Regards,
Markus
