[SCSI] libosd: osd_req_{read,write} takes a length parameter
For supporting of chained-bios we can not inspect the first bio only, as before. Caller shall pass the total length of the request, ie. sum_bytes(bio-chain). Also since the bio might be a chain we don't set it's direction on behalf of it's callers. The bio direction should be properly set prior to this call. So fix a couple of write users that now need to set the bio direction properly [In this patch I change both library code and user sites at exofs, to make it easy on integration. It should be submitted via James's scsi-misc tree.] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> CC: Jeff Garzik <jeff@garzik.org> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
