Thanks for reworking the commit message.

You should include a version number in the Subject: line, so we can
keep track of the different versions:

https://docs.kernel.org/process/submitting-patches.html

See the Section about "Subject Line".

Also, you should include a brief history of the patches, what changed
between each version under the --- marker.

There is no need to resend, please just remember these things for you
next patch you submit.
