Hello Christoph,
That blk_execute_rq() call can only be reached if a few lines above 0 was
assigned to the "error" variable. Since nfsd4_scsi_identify_device() returns
the value of the "error" variable I think -EIO should be assigned to that
variable before the "goto out_put_request" statement is reached.
Bart.
