    [SCSI] sas_ata: ata_post_internal should abort the sas_task · 1c50dc83
    Darrick J. Wong authored
    This patch adds a new field, lldd_task, to ata_queued_cmd so that libata
    users such as libsas can associate some data with a qc.  The particular
    ambition with this patch is to associate a sas_task with a qc; that way,
    if libata decides to timeout a command, we can come back (in
    sas_ata_post_internal) and abort the sas task.
    
    One question remains: Is it necessary to reset the phy on error, or will
    the libata error handler take care of it?  (Assuming that one is written,
    of course.)  This patch, as it is today, works well enough to clean
    things up when an ATA device probe attempt fails halfway through the probe,
    though I'm not sure this is always the right thing to do.
