From 1b5a2bd0602010398cb473d1b821a9f1c1399caf Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Sun, 20 Jul 2008 13:12:16 -0700 Subject: [PATCH] fastboot: remove "wait for all devices before mounting root" delay In the non-initrd case, we wait for all devices to finish their probing before we try to mount the rootfs. In practice, this means that we end up waiting 2 extra seconds for the PS/2 mouse probing even though the root holding device has been ready since a long time. The previous two patches in this series made the RAID autodetect code do it's own "wait for probing to be done" code, and added "wait and retry" functionality in case the root device isn't actually available. These two changes should make it safe to remove the delay itself, and this patch does this. On my test laptop, this reduces the boot time by 2 seconds (kernel time goes from 3.9 to 1.9 seconds).
