The XFS setup for ./khugepaged all:file checks that the kernel supports XFS but not that mkfs.xfs is installed. When CONFIG_XFS_FS=y and xfsprogs is missing, mkfs.xfs and mount both fail, but SPLIT_HUGE_PAGE_TEST_XFS_PATH is assigned from mktemp -d and stays set. The test then runs against plain tmpfs and six subtests fail.
The script already has a skip path for this test, but it never runs because the path variable is always set. Check that mkfs.xfs exists before attempting the XFS setup.
