Setup of that test is trying different file system types, and it looks
at errno code of "mount -t $fs /dev/zero /mnt/$fs".

Test still PASSes. This report appears to be only about extra message in dmesg,
which wasn't there before:

# mount -t xfs /dev/zero /mnt/xfs
# dmesg -c
[  897.177168] /dev/zero: Can't open blockdev
