Hmm ... Since REQ_SECURE implied REQ_DISCARD doesn't this mean that we should include REQ_OP_SECURE_ERASE checking wherever REQ_OP_DISCARD is being checked now in drivers/scsi/sd.c ? (It's only in 3 spots so it's a quickie patch)
SCSI doesn't support secure erase operations. Only MMC really supports it, plus the usual cargo culting in Xen blkfront that's probably never been tested..
