I thought we weren't exposing VAS to userspace yet?

If we are then we need to get things straight WRT copy/paste abort.

No we should not be. This might be just a leftover hunk that should
be moved to a future series.

At the moment (as far as I understand) it should be limited to
preempt-disabled, process context, kernel users which avoids any
concern for switch_to.

Thanks,
