Merge branch 'net-remove-some-rcu_bh-cruft'
Eric Dumazet says:
====================
net: remove some rcu_bh cruft
There is no point using rcu_bh variant hoping to free objects faster,
especially hen using call_rcu() or kfree_rcu().
Disabling/enabling BH has a non-zero cost, and adds distracting
hot spots in kernel profiles eg. in ip6_xmit().
