Test device: partition (sdb1) in removable / USB flash disk (sdb)

$ ls -1d /sys/block/sdb/sdb1
/sys/block/sdb/sdb1

$ cat /sys/block/sdb/removable

eoan-proposed:
---

- PKNAME shows partition's parent/wholedisk.
- RM shows 1 for removable disk's partition.

$ dpkg -s util-linux | grep ^Version:
Version: 2.34-0.1ubuntu2.3

$ lsblk -no PKNAME /dev/sdb1
sdb

$ lsblk -no RM /dev/sdb1
 1

eoan-updates:
---

- PKNAME shows nothing.
- RM shows 0 despite it's actually a removable disk's partition.

$ dpkg -s util-linux | grep ^Version:
Version: 2.34-0.1ubuntu2.2

$ lsblk -no PKNAME /dev/sdb1

$ lsblk -no RM /dev/sdb1
