Subject: [PATCH 106/129] target: Set response format in INQUIRY response
|
|
|
|
commit ce136176fea522fc8f4c16dcae7e8ed1d890ca39 upstream.
|
|
|
|
Current SCSI specs say that the "response format" field in the standard
|
|
INQUIRY response should be set to 2, and all the real SCSI devices I
|
|
have do put 2 here. So let's do that too.
