Subject: [PATCH] selftests/mm: skip khugepaged file tests if mkfs.xfs is unavailable
Date: Fri, 11 Sep 2026 14:45:17 +0200 [thread overview]
Message-ID: <20260911124517.63714-1-jaeyeon.lee.dev@gmail.com> (raw)
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.
