net: add dev_net_rcu() helper
[ Upstream commit 482ad2a4ace2740ca0ff1cbc8f3c7f862f3ab507 ]
dev->nd_net can change, readers should either
use rcu_read_lock() or RTNL.
We currently use a generic helper, dev_net() with
no debugging support. We probably have many hidden bugs.
Add dev_net_rcu() helper for callers using rcu_read_lock()
protection.
