Either delete the benchmark test files or, in 2.6, use fsync+posix_fadvise(POSIX_FADV_DONTNEED); - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
