Hello, Michael,
Just curious about the purpose of the rcu_dereference_index_check() in
vhost_has_feature(). I don't see how it fits in. The closest thing
I see if the use in handle_rx(), where it selects vq->log or NULL. But
in that case, I would expect the usual RCU usage pattern to wrap an
rcu_dereference() around the vq->log.
Enlightenment?
Thanx, Paul
