The 'sd' driver is calling scsi_mode_sense() to figure out
internal details. But scsi_mode_sense() never checks for
any pending unit attentions, so we're getting annoying error
messages like:

and a possible wrong decision for device cache

Here should be an explanation why is this needed.
The driver knows the fw version and can adapt to it.
When sending the version to firmware fails, the driver
just logs it and is able to continue.
Why is the information needed for the fw ?

Hi Nic,
lio-target is very minimalistic when it comes to generate UAs;
primarily they are generated for persistent reservations, but
generic changes tend to be ignored.
This patchset updates the UA handling and generates UA for internal
state changes (REPORTED LUNS DATA CHANGED, INQUIRY DATA
When changind the LUN inventory via core_enable_device_list_for_node()
or core_disable_device_list_for_node() a REPORTED LUNS DATA HAS CHANGED
UA should be send.
