Please for give me. I know that the name is misleading. The
Scatter-List here is the osd scatter-list. Which describes
extents on the object, not of the memory. The proper name would
be extents API. The reason we named it SG is because this is the
way the OSD standard names it. We keep very close with the STD
naming convention, so it ended up this way.
