The internal object is a collection of struct pages and so is intrinsically linked to the available physical memory on the machine, and not an arbitrary type from the uabi. Use phys_addr_t so the link between size and memory consumption is clear, and then double check that we don't overflow the maximum object size. v2: Also assert that size is not zero - a mistake I made a few times while writing selftests.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
