nouveau will benefit from this patchset and is already upstream in 5.1
so i am not sure what kind of pointer i can give for that, it is already
there. amdgpu will also benefit from it and is queue up AFAICT. ODP RDMA
is the third driver and i gave link to the patch that also use the 2
new functions that this patchset introduce. Do you want more ?

I guess i will repost with updated ack as Felix, Jason and few others
told me they were fine with it.

:( i did not know the tree they pull that in was fed into next. I will
discourage them from doing so going forward.

What more do you want to see ? I can repost with the ack already given
and the improve commit wording on some of the patch. But from user point
of view nouveau is already upstream, ODP RDMA depends on this patchset
and is posted and i have given link to it. amdgpu is queue up. What more
do i need ?

Cheers,
Jérôme
