+ * uverbs_alloc_spec_tree - Merges different common and driver specific feature
+ * into one parsing tree that every uverbs command will be parsed upon.
+ *
+ * @num_trees: Number of trees in the array @trees.
+ * @trees: Array of pointers to tree root definitions to merge. Each such tree
+ * possibly contains objects, methods and attributes definitions.
+ *
+ * Returns:
+ * uverbs_root_spec *: The root of the merged parsing tree.
+ * On error, we return an error code. Error is checked via IS_ERR.
+ *
+ * The following merges could take place:
+ * a. Two trees representing the same method with different handler
+ * -> We take the handler of the tree that its handler != NULL
+ * and its index in the trees array is greater. The incentive for that
+ * is that developers are expected to first merge common trees and then
+ * merge trees that gives specialized the behaviour.
+ * b. Two trees representing the same object with different
+ * type_attrs (struct uverbs_obj_type):
+ * -> We take the type_attrs of the tree that its type_attr != NULL
+ * and its index in the trees array is greater. This could be used
+ * in order to override the free function, allocation size, etc.
+ * c. Two trees representing the same method attribute (same id but possibly
+ * different attributes):
+ * -> ERROR (-ENOENT), we believe that's not the programmer's intent.
+ *
+ * An object without any methods is considered invalid and will abort the
+ * function with -ENOENT error.
