Subject: ixgbe: replace rtnl_lock with rcu_read_lock
Date: Sun,  5 Jun 2016 17:14:50 +0800	[thread overview]
Message-ID: <1465118091-6233-1-git-send-email-zyjzyj2000@gmail.com> (raw)


Hi,all

 I am using the ixgbe nic. I found that the rtnl_lock is being 
 used to enable upper device, such as macvlan. I am curious
 why rcu_read_lock is not used here.

 I replaced rtnl_lock with rcu_read_lock here. Then I made tests and
 it can work well.

 So can the rtnl_lock be replaced with rcu_read_lock?
 Anyone can explain it in details?

 Any reply is appreciated.
