[SCSI] libosd: write/read_sg_kern API
This is a trivial addition to the SG API that can receive kernel pointers. It is only used by the out-of-tree test module. So it's immediate need is questionable. For maintenance ease it might just get in, as it's very small. John. do you need this in the Kernel, or is it only for osd_ktest.ko? Signed-off-by: John A.
