Hi folks,
This is the fourth version of the media IOCTL handling rework set. What's
changed since v3:
patch 1:
- Use BUILD_BUG_ON() and ARRAY_SIZE() to ensure the ioctl array and the
equivalent compat array are always in sync. (This caused quite a few
conflicts with the rest of the patches.)
patch 5:
- Don't use unlikely().
- Fix commit message --- the patch was changed to use supported IOCTL sizes
but the commit message was not updated.
---
The patches themselves have been reworked so I don't detail the changes
in this set. What's noteworthy however is that the set adds support for
variable length IOCTL arguments.
(The motivation for these patches is having found myself pondering whether
to have nine or thirteen reserved fields for the request IOCTL. I decided
to address the problem instead. If this is found workable on the media
controller we could follow the same model on V4L2.)

Kind regards,
Sakari
