From: Mike Christie <michaelc@xxxxxxxxxxx>
This patch converts zfcp to the blk bsg lib. The differences
visible to the driver are:
- fc_bsg_job is now named bsg_job.
- no rport pointer. Can access it through the device pointer.
- the request and reply pointers on the scsi_bsg_job struct
are now void pointers, so you cannot do bsg_job->request->some_field.
Patch is only compile tested and made over scsi-misc.
