The v4l2_ext_controls ioctl handlers use an indirect pointer to an incompatible data structure, making the conversion particularly tricky. Moving the compat implementation to use the new v4l2_compat_get_user()/v4l2_compat_put_user() helpers makes it noticeably simpler. In v4l2_compat_get_array_args()/v4l2_compat_put_array_args(), the 'file' argument needs to get passed to determine the exact format, which is a bit unfortunate, as no other conversion needs these.

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
