From 875352c94224c88f5aa28cb77206f993bd31b7a2 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 10 May 2010 17:14:24 -0700 Subject: [PATCH] mm: remove all rcu head initializations Remove all rcu head inits. We don't care about the RCU head state before passing it to call_rcu() anyway. Only leave the "on_stack" variants so debugobjects can keep track of objects on stack.
