From 0e0fc1c23e04c15e814763f2b366e92d87d8b95d Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 11 Nov 2009 11:28:06 -0800 Subject: [PATCH] rcu: Mark init-time-only rcu_bootup_announce() as __init Because rcu_bootup_announce() is used only at boot time, mark it as __init, presumably so that its memory can be reclaimed.
