On my test laptop, this reduces the boot time +by 2 seconds (kernel time goes from 3.9 to 1.9 seconds). + +Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> +--- +--- + init/do_mounts.c | 3 +++ + 1 file changed, 3 insertions(+) + +Index: linux-2.6.29/init/do_mounts.c +=================================================================== +--- linux-2.6.29.orig/init/do_mounts.c ++++ linux-2.6.29/init/do_mounts.c +@@ -370,6 +370,7 @@ void __init prepare_namespace(void) + ssleep(root_delay); + } + ++#if 0 + /* + * wait for the known devices to complete their probing + * +@@ -378,6 +379,8 @@ void __init prepare_namespace(void) + * for the touchpad of a laptop to initialize. + */ + wait_for_device_probe(); ++#endif ++ async_synchronize_full(); + + md_run_setup(); + |
