Jason Wang e9cb423913 vhost: use mutex_lock_nested() in vhost_dev_lock_vqs() ... We used to call mutex_lock() in vhost_dev_lock_vqs() which tries to hold mutexes of all virtqueues. This may confuse lockdep to report a possible deadlock because of trying to hold locks belong to same class. Switch to use mutex_lock_nested() to avoid false positive.
