    Subject[patch 04/18] SCSI: add missing cdb clearing in scsi_execute()
    -stable review patch.  If anyone has any objections, please let us know.

    From: Tejun Heo <>

    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.
