McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Thu, 8 Jun 2017 18:52:26 -0700 rcu: Flag need for rcu_node_tree.h and rcu_segcblist.h visibility The rcu_node_tree.h and rcu_segcblist.h header files in the include/linux directory might appear at first sight to be internal to the RCU implementation. However, the definitions in these files are needed to determine the size of TREE SRCU's srcu_struct structure, so they must be externally visible, which is why they live in include/linux. This commit adds comments to this effect to those files. Signed-off-by: Paul E.
