Please note, that this will need a change (attached) while
applying to the mainline kernel because of API changes [1].

Unfortunately, current Xen tip kernel tree is v4.17-rc5 based,
so I cannot make the change in this patch now.
I don't see any chance this series could go into 4.18, as the merge
window is just closing. So please post the patch based on current
Linux master of torvalds/linux.git
Ok, I'll wait for any comments/r-b's and then rebase to
torvalds/linux.git and push v5?
As I mentioned earlier, I would very much like at least a review of the
new interfaces by someone more knowledgeable than me.
I am adding "DMA BUFFER SHARING FRAMEWORK" maintainer to the list.
Sumit, could please help reviewing this? The whole work here
is to add dma-buf to Xen's grant device driver.

Intel could probably also say couple of words as they also
might re-use this work.

BTW, is there any plan to rebase Xen tip kernel?

It is typically rebased to rc5 or r6, at which point patches for the
next merge window are applied.
