void debugfs_remove_recursive(struct dentry * dentry);

This function recursively removes a directory tree in debugfs that was previously created with a call to another debugfs function (like debugfs_create_file or variants thereof.)
This function is required to be called in order for the file to be removed, no automatic cleanup of files will happen when a module is removed, you are responsible here.
