[PATCH 0/6] Experimental P2P buffer sharing v3

[Felix Kuehling]

I think we had verbal agreement at our meeting in Markham that this
patch series is probably OK to submit. But I still don't have an
official "go ahead and submit".

Patch #1 has been reviewed by Daniel and Christian and should be good to go.

Patch #2, 4, 5 are reviewed by me, but I'd prefer to have an Acked-by an
amdgpu developer.

Patch #3, 6 are signed off by both me and Christian and need someone
else's Acked-by or Reviewed-by.

In patch 4 I needed to move some stuff around after Christian moved
struct amdgpu_bo into amdgpu_object.h Do you want me to resend the whole
patch series rebased on current amd-kfd-staging-4.11?

Thanks,
  Felix
