Well this means also that sys_mbind and sys_set_mempolicy are also broken because these functions also use get_nodes().
Fixing get_nodes() to do the proper thing would fix all of these without having to touch sys_migrate_pages or creating a compat_ function (which usually is placed in kernel/compat.c) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
