SubjectRe: [PATCH scsi-misc-2.6 02/05] scsi: remove REQ_SPECIAL in scsi_init_io()
Date
02_scsi_REQ_SPECIAL_semantic_scsi_init_io.patch

scsi_init_io() used to set REQ_SPECIAL when it fails sg
allocation before requeueing the request by returning
BLKPREP_DEFER. REQ_SPECIAL is being updated to mean special
requests. So, remove REQ_SPECIAL setting.
