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.

There is no need to validate the hugetlb page's refcount before trying to freeze the hugetlb page's expected refcount, instead we can just rely on the page_ref_freeze() to simplify the validation. Moreover we are always under the page lock when migrating the hugetlb page mapping, which means nowhere else can remove it from the page cache, so we can remove the xas_load() validation under the i_pages lock.
