From 00a74e44dc3f7656f23719aa978d035a2b33c038 Mon Sep 17 00:00:00 2001

Subject: [PATCH] fs: prioritize ext4 rootfs type
This would allow us to go directly to ext4 type rootfs checks
otherwise ext3 and ext2 will be tried first. This gives a
performance benefit in our case where our RootFS is known
to be ext4.
