Help to condense/optimize some working code

WordPress by default shows ALL posts to users who are Authors. I wanted Authors to only be able to see their own posts so I came up with the following code which works well.

Any suggestions to condense/optimize it?

// Only show posts related to current author
add_action('pre_get_posts', 'query_set_only_author' );
function query_set_only_author( $wp_query ) {
    global $current_user;
    if ( is_admin() && !current_user_can('edit_others_posts') ) {
        $wp_query->set( 'author', $current_user->ID );
    }
}

// Check that user is not an Administrator
if (!current_user_can('promote_users')) {
    add_filter('views_edit-post', 'remove_mine');
    add_filter('views_edit-post', 'posts_all');
    add_filter('views_edit-post', 'posts_published');
    add_filter('views_edit-post', 'posts_draft');
    add_filter('views_edit-post', 'posts_pending');
    add_filter('views_edit-post', 'posts_trash');
}

// Remove "Mine" from filter bar
function remove_mine( $views ) {
    unset($views['mine']);
    return $views;
}

// Fix "All" post count to only include posts related to current author
function posts_all($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == NULL ) $class = ' class="current"';
    $link = sprintf(__('<a href="%s"'.$class.'>All <span class="count">(%d)</span></a>', 'all'),
            admin_url('edit.php?post_type=post'),
            $result->found_posts);
    $views['all'] = $link;
    return $views;
}

// Fix "Published" post count to only include posts related to current author
function posts_published($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'publish',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'publish' ) $class = ' class="current"';
    $link = sprintf(__('<a href="%s"'.$class.'>Published <span class="count">(%d)</span></a>', 'publish'),
            admin_url('edit.php?post_status=publish&post_type=post'),
            $result->found_posts);
    $views['publish'] = $link;
    return $views;
}

// Fix "Drafts" post count to only include posts related to current author
function posts_draft($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'draft',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'draft' ) $class = ' class="current"';
        $link = sprintf(__('<a href="%s"'.$class.'>Draft'.((sizeof($result->posts)>1)?"s":"").' <span class="count">(%d)</span></a>', 'draft'),
            admin_url('edit.php?post_status=draft&post_type=post'),
            $result->found_posts);
    $views['draft'] = $link;
    return $views;
}

// Fix "Pending" post count to only include posts related to current author
function posts_pending($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'pending',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'pending' ) $class = ' class="current"';
        $link = sprintf(__('<a href="%s"'.$class.'>Pending <span class="count">(%d)</span></a>', 'pending'),
            admin_url('edit.php?post_status=pending&post_type=post'),
            $result->found_posts);
    $views['pending'] = $link;
    return $views;
}

// Fix "Trash" post count to only include posts related to current author
function posts_trash($views) {
    global $current_user;   
    $query = array(
        'author'       => $current_user->ID,
        'post_status'  => 'trash',
        'post_type'    => 'post'
    );
    $result = new WP_Query($query);
    if ( get_query_var('post_status') == 'trash' ) $class = ' class="current"';
    $link = sprintf(__('<a href="%s"'.$class.'>Trash <span class="count">(%d)</span></a>', 'trash'),
            admin_url('edit.php?post_status=trash&post_type=post'),
            $result->found_posts);
    $views['trash'] = $link;
    return $views;
}
