v3 was sent, with updated comments and expanded CC list.
The patch is against 3.9.4, though I assume it will apply to the upstream kernel easily enough.
I didn't want to add a link to the email thread.. The commit message and patch has enough info that I think an interested party could find the email thread easily enough if they needed more history.
And, much of the email thread is me running in circles thinking I am going insane :)
Thanks, Ben
