Shivank Garg 0b43b8bc8e mm/khugepaged: clean up refcount check using folio_expected_ref_count()
Use folio_expected_ref_count() instead of open-coded logic in
is_refcount_suitable().  This avoids code duplication and improves
clarity.

Drop is_refcount_suitable() as it is no longer needed.

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.
