Re: [PATCH scsi-misc-2.6 02/13] scsi: don't turn on REQ_SPECIAL on sgtable allocation failure.

[Tejun Heo]

02_scsi_no_REQ_SPECIAL_on_sgtable_allocation_failure.patch

	Don't turn on REQ_SPECIAL on sgtable allocation failure.  This
	was the last place where REQ_SPECIAL is turned on for normal
	requests.
