Display only author posts in dashboard all posts panel

Question

I would like to display only authors own posts in dashboard all posts section. As of now it displays everything.

I found some code here which is written by @t31os Its working correctly.

function posts_for_current_author($query) {
    global $user_level;

    if($query->is_admin && $user_level < 5) {
        global $user_ID;
        $query->set('author',  $user_ID);
        unset($user_ID);
    }
    unset($user_level);

    return $query;
}
add_filter('pre_get_posts', 'posts_for_current_author');

But user_level is deprecated. So can anyone modify the code for new version? Thanks

The following worked for me to show only the current user's posts in the admin

add_action( 'load-edit.php', 'posts_for_current_author' );
function posts_for_current_author() {
    global $user_ID;

    /*if current user is an 'administrator' do nothing*/
    //if ( current_user_can( 'add_users' ) ) return;

    /*if current user is an 'administrator' or 'editor' do nothing*/
    if ( current_user_can( 'edit_others_pages' ) ) return;

    if ( ! isset( $_GET['author'] ) ) {
        wp_redirect( add_query_arg( 'author', $user_ID ) );
        exit;
    }

}

It can be edited pretty easily if the restriction should only happen for users in a particular role.
