After doing this, it becomes clear that the RCU_SAVE_COMPLETED leg of the force_quiescent_state() function's switch statement is almost completely a no-op. A small change to the RCU_SAVE_DYNTICK leg renders it a complete no-op, after which it can be removed. Doing so also eliminates the forcenow local variable from force_quiescent_state().
