Patch series "Better split_huge_page_test result check", v5. This patchset uses kpageflags to get after-split folio orders for a better split_huge_page_test result check[1]. The added gather_after_split_folio_orders() scans through a VPN range and collects the numbers of folios at different orders. check_after_split_folio_orders() compares the result of gather_after_split_folio_orders() to a given list of numbers of different orders. This patchset also adds new order and in folio offset to the split huge page debugfs's pr_debug()s; This patch (of 5): They are useful information for debugging split huge page tests.

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.
