The inode since ioctl was the last user of the btree. It doesn't yet work because the item cache doesn't know how to search for items by sequence yet. It's not yet clear exactly how we'll build the data since ioctls. It'll be easy enough to refactor the inode since item walk if they follow a similar pattern again.
