Test steps are described in comment #6.

Only one filesystem (ext4) is detected:

# udevadm test-builtin blkid /sys/block/$(basename $dev)/$(basename $part)
...
ID_FS_UUID=aadbf085-7ce7-43e4-a149-ad11d997b710
ID_FS_UUID_ENC=aadbf085-7ce7-43e4-a149-ad11d997b710
ID_FS_VERSION=1.0
ID_FS_TYPE=ext4
ID_FS_USAGE=filesystem
...

# echo $?
0

The verbose log shows nilfs is not detected:

# LIBBLKID_DEBUG=all udevadm test-builtin blkid /sys/block/$(basename $dev)/$(basename $part)
