Subject: target: Return correct sense data for IO past the end of a device
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=09ceadc70383a4105c0372f9e83da2c0cb0a8017;p=linux-beck.git

target: Return correct sense data for IO past the end of a device

We should use TCM_ADDRESS_OUT_OF_RANGE (-> sense data LOGICAL BLOCK
ADDRESS OUT OF RANGE) for IOs past the end of a device instead of
INVALID FIELD IN CDB.
