It's as simple as tracing __get_user() usage in vhost process?
Thanks
Well there are now mtu notifiers etc etc. It's hardly as well
contained as that.
We can setup filter out exactly what sets of function that we wan to
trace. E.g we can only trace the usage of __get_user() and
invalidate_range_start(). This should be sufficient.
In the long run, we may want to have some tracepoints for vhost_net.
Thanks
