i have tried using many hooks to achieve this , i don't want one of my post meta to be updated when we update post  .

i tried doing something like :

add_filter( 'update_post_metadata', 'wpse_163859', 10, 5 );
function wpse_163859( $check, $object_id, $meta_key, $meta_value, $prev_value )
{
    return false;
}

i tried looking at meta.php in wp-includes  , tried whole day with lots of code  , appreciate any help  .
