I can't allow this for two reasons:
1) Userspace explicitly initializing all members will now get a compile
failure on the reference to ->reserved1
2) Userspace not initiailizing reserved fields, which worked previously,
might send in flags that trigger the new behavior.
Sorry, this is UAPI breakage.
