Subject: [PATCH] qemuProcessRefreshDisks: Don't skip filling of disk
|
|
|
735c6b |
information if tray state didn't change
|
|
|
735c6b |
|
|
|

Commit 5ef2582646eb98 added emitting of even when refreshign disk state,
|
|
|
735c6b |
where it wanted to avoid sending the event if disk state didn't change.
|
|
|
735c6b |
This was achieved by using 'continue' in the loop filling the
|
|
|
735c6b |
information. Unfortunately this skips extraction of whether the device
|
|
|
735c6b |
has a tray which is propagated into internal structures, which in turn
|
|
|
735c6b |
broke cdrom media change as the code thought there's no tray for the
|
|
|
735c6b |
device.
