This is wrong.\n\nWith this patch we restore the \"!= &nfsd_lease_mng_ops\" case to behave\nas it did before the change mentioned below. This is the same as the\ncurrent code, but without any reference to a possible delegation."

Esto es incorrecto. Con este parche restauramos el caso \"!= &nfsd_lease_mng_ops\" para que se comporte como lo hac\u00eda antes del cambio mencionado a continuaci\u00f3n. Esto es lo mismo que el c\u00f3digo actual, pero sin ninguna referencia a una posible delegaci\u00f3n."
