      block: set rq->resid_len to blk_rq_bytes() on issue · 5f49f631
      Tejun Heo 提交于
      In commit c3a4d78c, while introducing
      rq->resid_len, the default value of residue count was changed from
      full count to zero.  The conversion was done under the assumption that
      when a request fails residue count wasn't defined.  However, Boaz and
      James pointed out that this wasn't true and the residue count should
      be preserved for failed requests too.
      
      This patchset restores the original behavior by setting rq->resid_len
      to blk_rq_bytes(rq) on request start and restoring explicit clearing
      in affected drivers.  While at it, take advantage of the fact that
      rq->resid_len is set to full count where applicable.
      
      * ide-cd: rq->resid_len cleared on pc success
      
      * mptsas: req->resid_len cleared on success
      
      * sas_expander: rsp/req->resid_len cleared on success
      
      * mpt2sas_transport: req->resid_len cleared on success
      
      * ide-cd, ide-tape, mptsas, sas_host_smp, mpt2sas_transport, ub: take
        advantage of initial full count to simplify code
      
      Boaz Harrosh spotted bug in resid_len initialization.  Fixed as
      suggested.
