Qubes OS release

Qubes OS 4.2, Qubes OS 4.3

Brief summary

When a qube changes the device name for a dm block device, eg. by removing the dm device and creating a new one using the same dm device node, the qui-devices widget continues to use the old name. The output of qvm-block list does show the correct, new name. Restarting the widget in dom0 (systemctl --user restart [email protected]) upadates to the correct dm name. So I suspect its a caching issue in the widget.

Steps to reproduce

In domN:

1. truncate -s 1M test
2. DEV=$(losetup --show -f test)
3. echo "0 1 linear ${DEV} 0"|dmsetup create test1
4. dmsetup remove test1
5. echo "0 1 linear ${DEV} 0"|dmsetup create test2

In GUI:

1. Click on qui-devices widget and see that the device still shows as test1

Expected behavior

The widget should be updated with the correct dm name always.

Actual behavior

The widget uses the old dm name.
