Re: [PATCH v2] ksm_tests: Skip hugepage test when Transparent Hugepages are disabled

Some systems (e.g. minimal or real-time kernels) may not enable Transparent Hugepages (THP), causing MADV_HUGEPAGE to return EINVAL. This patch introduces a runtime check using the existing THP sysfs interface and skips the hugepage merging test (`-H`) when THP is not available.

To avoid those failures:

But we deliberately have in tools/testing/selftests/mm/config:

CONFIG_TRANSPARENT_HUGEPAGE=y

So isn't this rather a test setup issue? Meaning, the environment is not well prepared.
