There are a few discussions left with regards to this ioctl:

1) the name of the new structs will contain _v2_ on it?
2) what's the best alternative to avoid compat32 issues?

Due to that, let's postpone the addition of this new ioctl to
the next Kernel version, to give people more time to discuss it.

I thought we discussed this in our irc meeting and
arrived at a good solution for compat32 issue

My recommendation is getting this ioctl into 4.5 with
a warning that it could change. The reason for that is
that this ioctl helps with testing the media controller
v2 api. Without this API, we won't see much testing from
userspace in 4.5

People will ignore the warning, that never works :(
