[SCSI] sas_ata: Assign sas_task to scsi_cmnd to enable EH for ATA devices
The SATL should connect the scsi_cmnd to the sas_task (despite the presence of libata) so that requests to abort scsi_cmnds headed to the ATA device can be processed by the EH and aborted correctly. The abort status should still be propagated from sas -> ata -> scsi. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
