Example migrated from Codex:

The example below sets the number of revisions for a theoretical post type ‘my_custom_post’.
```
add_filter( 'wp_revisions_to_keep', 'filter_function_name', 10, 2 );

function filter_function_name( $num, $post ) {
    
    if( 'my_custom_post' == $post->post_type ) {
        $num = 5;
    }
    return $num;
}
```
