Then have LTP record what min_free_kbytes was at the same time THP was enabled by the test and restore both settings. It leaves a window where an admin can set an alternative value during the test but that would also invalidate the test in same cases and gets filed under "don't do that". -- Mel Gorman SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
