This is pretty straight forward - we define a new item type, SCOUTFS_ORPHAN_KEY. We don't need to store any value with this, the inode and type fields are enough for us to find what inode has been orphaned. Otherwise this works as one would expect. Unlink sets the item, and ->evict_inode removes it. On mount, we scan for orphan items and remove any corresponding inodes.
