We avoid calling __mod_node_page_state(NR_FILE_PAGES) for hugetlb page now, but it's not enough because later code doesn't handle hugetlb properly. Actually in our testing, WARN_ON_ONCE(PageDirty(page)) at the end of this function fires for hugetlb, which makes no sense. So we should return immediately for hugetlb pages.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
