Other than this patch not applying, nah, I think it's all good ;P. I
guess base-commit: 9eba3a9ac9cd5922da7f6e966c01190f909ed640 is
somewhere in a local tree of yours. There are quite a few conflicts
and I don't think it would build even if based on the right tree,
e.g.,  KVM_CAP_GUEST_MEMFD_MMAP is a rename of KVM_CAP_GMEM_MMAP,
rather an addition of an undeclared identifier.

That said, I think I understand what you mean, and I can apply the
spirit of this patch.

Stay tuned for v16.
