+ * ntfs_read_locked_index_inode - read an index inode from its base inode
+ * @base_vi:	base inode
+ * @vi:		index inode to read
+ *
+ * ntfs_read_locked_index_inode() is called from ntfs_index_iget() to read the
+ * index inode described by @vi into memory from the base mft record described
+ * by @base_ni.
+ *
+ * ntfs_read_locked_index_inode() maps, pins and locks the base inode for
+ * reading and looks up the attributes relating to the index described by @vi
+ * before setting up the necessary fields in @vi as well as initializing the
+ * ntfs inode.
+ *
+ * Note, index inodes are essentially attribute inodes (NInoAttr() is true)
+ * with the attribute type set to AT_INDEX_ALLOCATION.  Apart from that, they
+ * are setup like directory inodes since directories are a special case of
+ * indices ao they need to be treated in much the same way.  Most importantly,
+ * for small indices the index allocation attribute might not actually exist.
+ * However, the index root attribute always exists but this does not need to
+ * have an inode associated with it and this is why we define a new inode type
+ * index.  Also, like for directories, we need to have an attribute inode for
+ * the bitmap attribute corresponding to the index allocation attribute and we
+ * can store this in the appropriate field of the inode, just like we do for
+ * normal directory inodes.
+ *
+ * Q: What locks are held when the function is called?
+ * A: i_state has I_LOCK set, hence the inode is locked, also
+ *    i_count is set to 1, so it is not going to go away
+ *
+ * Return 0 on success and -errno on error.  In the error case, the inode will
+ * have had make_bad_inode() executed on it.
