Can we review this series properly?

Well, since it pretty much is what I suggested a few years ago, I
certainly won't NAK it.

And the patches looked very straightforward to me. Just the final
diffstat is worth quoting again because that certainly doesn't look
problematic:

  7 files changed, 33 insertions(+), 204 deletions(-)

and it removes that GIFT flag that was truly disgusting.

So I'm certainly ok with it from a "looking at the patch" standpoint.
I didn't _test_ it. I don't have any workload that might remotely
care.

I did a quick scan on debian code search for vmsplice, and after ten
pages of entries that weren't actually *using* it but had lists of
system calls, I grew bored. So there are likely users, but I don't
know what they are and how much they care. It *might* be a big
performance issue somewhere. Unlikely, but...
