It is used to test split_huge_page_to_list_to_order for pagecache THPs. Also add test cases for split_huge_page_to_list_to_order via both debugfs.

Hi Zi,
When booting the kernel against next-master(20240228)with Arm64 on Marvell Thunder X2 (TX2), the kselftest-mm test 'split_huge_page_test' is failing in our CI (with rootfs over NFS). I can send the full logs if required.
A bisect (full log below) identified this patch as introducing the failure. Bisected it on the tag "next-20240228" at repo "https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git".
This works fine on Linux version 6.8.0-rc6
Hi Aishwarya,
Can you try the attached patch and see if it fixes the failure? I changed the test to accept XFS dev as input, mount XFS on a temp folder under /tmp, and skip if no XFS is mounted.
Please try this updated one. It allows you to specify a XFS device path in SPLIT_HUGE_PAGE_TEST_XFS_PATH env variable, which is passed to split_huge_page_test in run_vmtests.sh. It at least allow CI/CD to run the test without too much change.
