Cannot make twentyeleven stop adding and tags

I am building a child them of twentyeleven. I have set up a functions.php file in my child them folder rather than screwing with the original. I have added

remove_filter( 'the_content', 'wpautop' );
remove_filter( 'the_excerpt', 'wpautop' );

to my new functions file, but wordpress still seems to want to add it’s tags. Am I missing something?
