[PATCH V2 5/5] vdpasim: vDPA device simulator
...ovide the release function.
Again the safest model is 'vdpa_alloc_device' which combines the
kzalloc and the vdpa_init_device() and returns something that is
error unwound with put_device()
The subsystem owns the release and does the kfree and other cleanup
like releasing the IDA.

[PATCH] vhost: fix default for vhost_iotlb
During randconfig build testing, I ran into a configuration that has
CONFIG_VHOST=m, CONFIG_VHOST_IOTLB=m and CONFIG_VHOST_RING=y, which
makes the iotlb implementation left out from vhost_ring, and in turn
leads to a link failure of the vdpa_sim module:

[PATCH V2 0/5] vDPA support
Hi all:
This is an updated version of kernel support for vDPA device. Various
changes were made based on the feedback since last verion. One major
change is to drop the sysfs API and leave the management interface for
future development, and introudce the incremental DMA bus
operations. Please see changelog for more information.
The work on vhost, IFCVF (intel VF driver for vDPA) and qemu is
