    block: cleanup tracing · 48b77ad6
    Christoph Hellwig authored
    A couple tweaks to the tracing code:
    
     - trace the request size for all requests
     - trace request sector and nr_sectors only for fs requests, enforced by
       helpers
     - drop SCSI CDB tracing - we have SCSI tracing for this and are going
       to me the CDB out of the generic struct request soon.
    
    With this the tracing code stops to know about BLOCK_PC requests entirely,
    it's just FS vs passthrough requests now, where the latter includes any
    driver-private requests.
