+ * scn_pausing - a scan that cannot be completed in a single txg or
+ * has exceeded its allotted time will need to pause.
+ * When this flag is set the scanner will stop traversing

+ *
+ * scn_restart_txg - directs the scanner to either restart or start a
+ * a scan at the specified txg value.
+ *
+ * scn_done_txg - when a scan completes its traversal it will set
+ * the completion txg to the next txg. This is necessary
+ * to ensure that any blocks that were freed during
+ * the scan but have not yet been processed (i.e deferred
+ * frees) are accounted for.
+ *
+ * This structure also maintains information about deferred frees which are
