Subject: ixgbe,rcu: convert call_rcu(ring_free_rcu) to kfree_rcu()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bcec8b6531d481ced35506517af69adb2399f2a4;p=openwrt%2Fstaging%2Fblogic.git

ixgbe,rcu: convert call_rcu(ring_free_rcu) to kfree_rcu()

The rcu callback ring_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(ring_free_rcu).
