Also nice :-) Here's my numbers (again with lots of debug enabled): old: [ 0.027087] Freeing SMP alternatives: 12k freed [ 6.835298] Freeing initrd memory: 8004k freed [ 18.820837] Freeing unused kernel memory: 1092k freed [ 18.838487] Freeing unused kernel memory: 1456k freed [ 18.850665] Freeing unused kernel memory: 1544k freed new: [ 0.025087] Freeing SMP alternatives: 12k freed [ 6.775349] Freeing initrd memory: 8004k freed [ 18.753519] Freeing unused kernel memory: 1144k freed [ 18.771447] Freeing unused kernel memory: 1508k freed [ 18.783637] Freeing unused kernel memory: 1544k freed Lets hope these pass all my tests. -- Steve -- 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/
