I've just realized I missed to add your recipient email to the series [1] sent
out just a few hours ago - sorry for that.  However, you can find some reply
instructions at the bottom of that page, e.g. import the mbox into your mail
client.

Please note this is a reworked version of the initial patches, fixing some
additional issues, hence retesting would be necessary.  For convenience, you may
also pick these patches from [2].

Regards,
Cristian
