Comment 6 for bug 2024114

https://bugzilla.redhat.com/show_bug.cgi?id=2143235#c4 has a nice reproducer which could be used in the test case, if you can confirm it works as advertised.

Basically:

1. Run "virsh nodedev-list" for 1000 times, and check the memory occupied by virtnodedevd service; The memory occupied increased from 13.9M to 24.0M after 8min;

#!/bin/sh
systemctl start virtnodedevd
systemctl status virtnodedevd
i=0
while [ $i -ne 1000 ]
do
 virsh nodedev-list
        i=$(($i+1))
        echo "$i"
done
systemctl status virtnodedevd

and watch the "Memory:" field grow (or not, if the fix is there).
