+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).
