Subject: RE: [PATCH iproute2] uapi: add missing virtio related headers
Hi Stephen,
vdpa headers were present in commit c2ecc82b9d4c at [1].
I added them at [1] after David's recommendation in [2].
Should we remove [1]?
Did you face compilation problem without this fix?
[1] ./vdpa/include/uapi/linux/vdpa.h
[2] https://lore.kernel.org/netdev/abc71731-012e-eaa4-0274-5347fc99c249@gmail.com/
