Use MGLRU's debugfs interface to do access tracking instead of page_idle. The logic to use the page_idle bitmap is left in, as it is useful for kernels that do not have MGLRU built in. When MGLRU is enabled, page_idle will report pages as still idle even after being accessed, as MGLRU doesn't necessarily clear the Idle folio flag when accessing an idle page, so the test will not attempt to use page_idle if MGLRU is enabled but otherwise not usable. Aging pages with MGLRU is much faster than marking pages as idle with page_idle.

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.
