Hi Everybody,
How to simulate the export function "virtqueue_add_buf"?
I tried to invoke it by pinging to the host machine, but failed.
Awaiting your replies !
Regards,
Devi.

Correct issue with not checking kmalloc return value.
This fix now only uses one receive buffer for all hv_utils
channels, and will do only one kmalloc on init and will return
with a -ENOMEM if kmalloc fails on initialize.
And properly clean up memory on failure.

Those are accessed without any kind of synchronization. I do not know
exact context, but are you sure it is single-threaded?
