This patchset fixes the issue on passing 'host_status' to the guest kernel.
The 1st patch fixes the erroneous usage of req->host_status. The 2nd patch is to pass the SCSI_HOST_ERROR to the guest kernel when the req->bus->info->fail() is not implemented. I do not add 'Fixes:' because I am not sure if to not pass SCSI_HOST_ERROR was on purpose, especially for security reason. Thank you very much! Dongli Zhang
