+Subject: [PATCH] lsblk: force to print PKNAME for partition
+
+PKNAME (parent kernel device name) is based on printed tree according
+to parent -> child relationship. The tree is optional and not printed
+if partition specified (.e.g "lsblk -o+PKNAME /dev/sda1"), but old
+versions print the PKNAME also in this case.
