Description Dusty Mabe 2019-09-11 15:59:18 UTC 
Description of problem:

We are using lsblk --output PKNAME and that appears to have stopped working properly in fedora 31+. Here is the output:

on F30 it works and properly shows `/dev/vda`
```
[vagrant@vanilla-f30 ~]$ lsblk --output PTUUID,PKNAME --pairs --paths --nodeps /dev/vda1
PTUUID="3175bbb3" PKNAME="/dev/vda"
[vagrant@vanilla-f30 ~]$ rpm -q kernel-core util-linux
kernel-core-5.0.9-301.fc30.x86_64
kernel-core-5.2.11-200.fc30.x86_64
util-linux-2.33.2-2.fc30.x86_64
```

on F31 PKNAME is blank:

[vagrant@vanilla-f31 ~]$ lsblk --output PTUUID,PKNAME --pairs --paths --nodeps /dev/vda1
PTUUID="539f29b0" PKNAME=""
[vagrant@vanilla-f31 ~]$ rpm -q kernel-core util-linux
kernel-core-5.3.0-0.rc6.git0.1.fc31.x86_64
util-linux-2.34-2.fc31.x86_64
```

on rawhide (F32) PKNAME is blank:

```
[vagrant@vanilla-rawhide ~]$ lsblk --output PTUUID,PKNAME --pairs --paths --nodeps /dev/vda1
PTUUID="f6214eaa" PKNAME=""                                                                 
[vagrant@vanilla-rawhide ~]$ rpm -q kernel-core util-linux                                  
kernel-core-5.3.0-0.rc8.git0.1.fc32.x86_64                                                  
util-linux-2.34-4.fc32.x86_64
```



Version-Release number of selected component (if applicable):

Comment 1 Karel Zak 2019-09-12 08:53:59 UTC 
This is already fixed in upstream tree, commit: http://github.com/karelzak/util-linux/commit/e3bb9bfb76c17b1d05814436ced62c05c4011f48

I'll backport it to f31+

Comment 5 Dusty Mabe 2019-09-12 16:46:07 UTC 
After upgrading all of my packages on the system that are provided by the util-linux rpm...

```
Upgrading:                                                                                          
 libblkid          x86_64   2.34-3.fc31
 libfdisk          x86_64   2.34-3.fc31
 libmount          x86_64   2.34-3.fc31
 libsmartcols      x86_64   2.34-3.fc31
 libuuid           x86_64   2.34-3.fc31
 util-linux        x86_64   2.34-3.fc31
```

It all seems to work!

```
[vagrant@vanilla-f31 tmp]$ lsblk --output PTUUID,PKNAME --pairs --paths --nodeps /dev/vda1
PTUUID="7ba0e2fb" PKNAME="/dev/vda"
```
