Subject: Disk UUID failing query in 4.14-rc5

There has been some change between the 4.13 and 4.14-rc5 kernel. I am
using the same userspace with those two kernels. 4.13 successfully
reports the UUID using 'blkid /dev/sdX' for all cases.

However, when I switch to the 4.14-rc5 kernel, I can successfully
query /dev/sda1 for the UUID. However, /dev/sda2 returns an error code
of 2. Very strange that it works for one and not the other.

I have ext3 filesystems using e2fsprogs-1.43.3 and util-linux-2.28.2.
