Take a first step towards untangling Linux kernel header files by placing the struct rcu_head definition into include/linux/types.h and including include/linux/types.h in include/linux/rcupdate.h where struct rcu_head used to be defined. The actual inclusion point for include/linux/types.h is with the rest of the #include directives rather than at the point where struct rcu_head used to be defined, as suggested by Mathieu Desnoyers. Once this is in place, then header files that need only rcu_head can include types.h rather than rcupdate.h. Signed-off-by: Paul E.
