Hello!
This series contains flavor-consolidation updates to RCU-sync:
1. Kill rcu_sync_type/gp_type, courtesy of Oleg Nesterov.
2. Use DEFINE_STATIC_PERCPU_RWSEM() to initialize dup_mmap_sem in
uprobes, courtesy of Oleg Nesterov.
3. Add DEFINE_PERCPU_RWSEM(), use it to initialize
cgroup_threadgroup_rwsem in percpu-rwsem, courtesy of Oleg Nesterov.
4. Simplify the state machine, courtesy of Oleg Nesterov.
Thanx, Paul
