Therefore the destroy\nfunctions are split into two: cancelling garbage collectors safely at\nexecuting the command received by netlink and moving the remaining\npart only into the rcu callback."

Pero elsync_rcu() agregado a la funci\u00f3n swap la ralentiza innecesariamente: se puede mover con seguridad para destruir y usar call_rcu() en su lugar. Eric Dumazet se\u00f1al\u00f3 que simplemente llamar a las funciones de destrucci\u00f3n como devoluci\u00f3n de llamada de rcu no funciona: los conjuntos con tiempo de espera usan recolectores de basura que necesitan cancelarse en la destrucci\u00f3n y que pueden esperar. Por lo tanto, las funciones de destrucci\u00f3n se dividen en dos: cancelar los recolectores de basura de forma segura al ejecutar el comando recibido por netlink y mover la parte restante solo a la devoluci\u00f3n de llamada de rcu."
