Subject: selftests/mm: skip khugepaged file tests if mkfs.xfs is unavailable
Date: Fri, 11 Sep 2026 14:45:17 +0200

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.
