Is this a plain resend, or did you address any of the reviews?
If you addressed any reviews please use 'PATCHv2' (instead of just 
'PATCH'), to indicate that this is an update to the previous version.

If it's a resend please state so, too (eg by using 'PATCH RESEND' or 
something).

And as this is just a single patch the cover letter is not required.

Cheers,

Hannes
