+ * passes zero to the filler function's offset. The filler
+ * function will not return '1' (unless an error happens), so the
+ * whole directory is read in a single readdir operation. This
+ * works just like the old getdir() method.
+ *
+ * 2) The readdir implementation keeps track of the offsets of the
+ * directory entries. It uses the offset parameter and always
+ * passes non-zero offset to the filler function. When the buffer
+ * is full (or an error happens) the filler function will return
+ * '1'.
