Hmm, no. We'll go use udmabufs for blob resources only, so this should
not be needed. Maybe squash this with patch #8?
take care,

Add helper functions to create a dmabuf for a resource and mmap it.
To be able to create a dmabuf using the udmabuf driver, Qemu needs
to be lauched with the memfd memory backend like this:
qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M
-machine memory-backend=mem1
