This is one is also a rude BUG_ON:
ret = vmbus_post_msg(msg, sizeof(struct vmbus_channel_close_channel));
BUG_ON(ret != 0);
vmbus_post_msg() hv_post_message() can easily return !0.
i.e. if this kmalloc() fails:
addr = (unsigned long)kmalloc(sizeof(struct aligned_input), GFP_ATOMIC);
if (!addr)
return -ENOMEM;
