We noticed the below oops since commit 68a25f08c9bec07ad95e55a01b127168e43aed84
("process_vm_access: take get_user_pages/put_pages one level up")
while running ltp tests inside kvm.

Actually, that's a combination of 3 bugs, only one of them being in this
commit. See current #iov_iter; AFAICS, all process_vm stuff in LTP passes
with it.
BTW, what's the story with ioctl3? What I'm getting from it is
"Must supply a file collection or a command", with no further
explanations. Something it wants installed that just isn't there?

I can't find this patch anywhere. Where did it come from?

It used to be in vfs.git#iov_iter; fixed since then, but this stuff is still
not in #for-next.
