+
+   Set nvme_root_t context

+**Parameters**
+
+``nvme_root_t r``
+  nvme_root_t context
+
+**Description**
+
+In order to be able to log from code paths where no root object is passed in
+via the arguments use the the default one which can be set via this call.
+When creating a new root object with **nvme_create_root** the global root object
+will be set as well. This means the global root object is always pointing to
+the latest created root object. Note the first **nvme_free_tree** call will reset
+the global root object.
