This patch looks good to me, but commit message is not good to me.
You should include three important things in one patch.
WHAT does this patch do: describe what does this patch do in title.
WHY this patch: describe why need this patch. I need a reason to apply this patch.
HOW to do: commit body would show how to do. HOW should be related to WHAT.
You does not show WHY need this patch.
Describe the reason why I need this patch.
Regards,
CK
