And, even if the patch's effect can be shown with little guest DRAM, the
test case still requires a multi-gig ivshmem-plain device. In
"tests/ivshmem-test.c", I see how it is set up -- the backend is set up
with shm_open(). The file created under /dev/shm (on Linux) might
require host RAM just the same as normal guest DRAM (especially with
memory overcommit disabled on the host), correct?
