*If* the conversion takes place only in v4l2-ioctl.c, then it makes sense have these structs + ioctls moved to v4l2-ioctl.h.
Ok.
I noticed that v4l2-compat-ioctl32.c wasn't changed. Is that right? I have unfortunately no time to double-check that, but it surprised me.
Yes, I pointed that out in the cover letter as something that is still left to be done. If we end up taking the current approach (plus the change to the location of the conversion), the compat code would basically be duplicated. Alternatively, the video_usercopy() function could just be changed to handle both 32-bit formats directly (including conversion of the multiplane array) and then we can remove that compat handler for all eight ioctls.
