Hi Ezequiel, John,

After creating extensive new compliance tests for this feature I am now
confident enough about the implementation.

You can find it here:

https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=ctrl-refactor

There are two items that I want to fix before I will post this:

1) The new flag needs to be documented
2) I think there are some simplifications possible w.r.t. storing the
  size of the new array, I want to look at that a bit more.

In the meantime it would be great if some testing of this series can be
done with real drivers instead of just vivid.

Well I finally managed to put together your patch (in 5.10), tweaked
driver & ffmpeg to have a variable noof slice headers and it all seems
to work well. With the code I have it doesn't give a significant
improvement in performance over 1 slice at a time but that is probably
because I have multithreaded userland code and take liberties with
buffer returns from the driver that Ezequiel disaproves of (but my
ffmpeg code is happy with).

I don't think I have ever disapproved anything (and if I made it sound like that, it was a mistake). Quite the opposite, I am more than supportive to see get more drivers merged upstream.

Thanks!
Ezequiel
