The third parameter to _IOR et al is a type name, not a size. So the parameter being named "size" is irritating. Rename it to "argtype" instead to reduce confusion. There is a very minor chance that this breaks stuff. It only hurts however if there is a variable (or macro) in userspace that is called "argtype" *and* it's used in the parameters of _IOR and friends. IMHO this is negligible because usually definitions making use of these macros are provided by kernel headers (i.e. us) or if they are replicated in userspace code, they are replicated and so supposed to match the kernel definitions (e.g. to make them usable by programs without the need to update the kernel headers used to compile the program).

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 reStructuredText 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.
