It doesn't have any callers anymore. Aside: The ->mmap/munmap hooks have a bit a confusing name, they don't do userspace mmaps, but a kernel vmap. I think most places use vmap for this, except ttm, which uses kmap for vmap for added confusion. mmap seems entirely for userspace mappings set up through mmap(2) syscall.

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.
