From c1935209df8c903fc3a33143223338826fa54bd1 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 12 Apr 2018 16:29:13 -0700 Subject: rcu: Simplify and inline cpu_needs_another_gp() Now that RCU no longer relies on failsafe checks, cpu_needs_another_gp() can be greatly simplified. This simplification eliminates the last call to rcu_future_needs_gp() and to rcu_segcblist_future_gp_needed(), both of which which can then be eliminated. And then, because cpu_needs_another_gp() is called only from __rcu_pending(), it can be inlined and eliminated. This commit carries out the simplification, inlining, and elimination called out above.
