Re: [Xen-devel] how to read value from xenstore inside kernel

[Kuriakose Mathew <kmathew123@xxxxxxxxx>]

The .node  member I initialized while declaring  and .callback I initialized in netbacl init function (just above where I use register_xenbus_watch )as  shown below. (used balloon.c as guideline)


static struct xenbus_watch target_watch =
{
    .node = "memory/target"
    
};

static int __init netback_init(void)
{
......
target_watch.callback = watch_target;
... register_xenbus_watch(&target_watch);
...
}

Thanks
Mathew

Please show the code where you initialize target_watch
