+Merges a snapshot into its origin volume. If both the origin and snapshot volume
+are not open the merge will start immediately. Otherwise, the merge will start
+the first time either the origin or snapshot are activated and both are closed.
+Merging a snapshot into an origin that cannot be closed, for example a root
+filesystem, is deferred until the next time the origin volume is activated.
+When merging starts, the resulting logical volume will have the origin's name,
+minor number and UUID. While the merge is in progress, reads or writes to the
+origin appear as they were directed to the snapshot being merged. When the
+merge finishes, the merged snapshot is removed.
