rtnl_lock() is being replaced with rtnl_net_lock() that
|
|
acquires the global RTNL and a small per-netns RTNL mutex.
|
|
|
|
During the conversion, rtnl_net_lock() just adds an extra
|
|
mutex in every RTNL scope and slows down the operations.
|
|
|
|
Once the conversion completes, rtnl_lock() will be removed
|
|
and rtnetlink will gain per-netns scalability.
