Matthew Wilcox (Oracle) 149fc78735 include/linux/sched/mm.h: use rcu_dereference in in_vfork() ... Fix a sparse warning by using rcu_dereference(). Technically this is a bug and a sufficiently aggressive compiler could reload the `real_parent' pointer outside the protection of the rcu lock (and access freed memory), but I think it's pretty unlikely to happen.
