Eric,

Your patch uses clock_gettime() to get the time for the tvc structure.

That's not sufficiently portable for us.

>From what I can see, the tvc structure and its predecessor code in the
old driver only care about how many seconds have passed, in order to do
a check against up->max_delay.

Do you have future plans for the tvc structure where higher-resolution
information will be useful?  Otherwise I'm inclined to revert the patch
in that area to go back to a time() call, as that easily gives us the
"seconds" we're looking for.
