+/**
+ * debugfs_create_symlink- create a symbolic link in the debugfs filesystem
+ * @name: a pointer to a string containing the name of the symbolic link to
+ * create.
+ * @parent: a pointer to the parent dentry for this symbolic link. This
+ * should be a directory dentry if set. If this paramater is NULL,
+ * then the symbolic link will be created in the root of the debugfs
+ * filesystem.
+ * @target: a pointer to a string containing the path to the target of the
+ * symbolic link.
+ *
+ * This function creates a symbolic link with the given name in debugfs that
+ * links to the given target path.
+ *
+ * This function will return a pointer to a dentry if it succeeds. This
+ * pointer must be passed to the debugfs_remove() function when the symbolic
+ * link is to be removed (no automatic cleanup happens if your module is
+ * unloaded, you are responsible here.) If an error occurs, %NULL will be
+ * returned.
+ *
+ * If debugfs is not enabled in the kernel, the value -%ENODEV will be
+ * returned.
