Subject[PATCH tip/core/rcu 0/11] rcu: suppress GP start to simplify force_quiescent_state()
Hello!

This patch series makes a sequence of changes that prevent a new RCU
grace period from starting while force_quiescent_state() is the the
process of trying to cause the prior grace period to complete. This
simplifies the code and eliminates numerous painful race conditions.

Thanx, Paul
