-stable review patch. If anyone has any objections, please let us know.
------------------
From: Tejun Heo <[email protected]>
Clear-garbage-after-CDB patch missed scsi_execute() and it causes some
ODDs (HL-DT-ST DVD-RAM GSA-H30N) choke during SCSI scan. Note that
this patch is only for -stable. There is another more reliable fix
for this problem proposed for devel tree.
