+ * Eraseblock Chain
+ *
+ * A linked list structure to order eraseblocks by volume and logical number
+ * and to update by version number. Doesn't contain actual eraseblock data
+ * but rather the erasecounter and volume id headers as well as a position
+ * indicator.
+ *
+ * Diagram Example:
+ *
+ * [V1.0v0]->[V1.1v2]->[V1.2v1]->[V2.0v2]->[V2.1v0]->[V2.2v1]->NULL
+ * | | | | | |
+ * NULL [V1.1v1] [V1.2v0] [V2.0v1] NULL [V2.2v0]
+ * | | | |
+ * [V1.1v0] NULL [V2.0v0] NULL
+ * | |
+ * NULL NULL
+ *
+ * [VA.BvC] represents the eb_info for the eraseblock with the vol_id A,
+ * lnum B and leb_ver C
+ * -> represents the `next' pointer
+ * | represents the `older' pointer
