Description

Currently, the ldiskfs otable-based iteration only returns namespace visible objects. That means the OSD needs to distinguish the FID/object visibility. But the OSD should not has the knowledge about the FID/object visibility. It is the iteration caller's duty to distinguish that by itself.
