Add huge_memory:trace_mm_khugepaged_scan_file tracepoint to hpage_collapse_scan_file() analogously to hpage_collapse_scan_pmd(). While this change is targeted at debugging MADV_COLLAPSE pathway, the "mm_khugepaged" prefix is retained for symmetry with huge_memory:trace_mm_khugepaged_scan_pmd, which retains it's legacy name to prevent changing kernel ABI as much as possible.

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.
