[PATCH] selinux: remove all rcu head initializations

From: Paul E. McKenney
Date: Tue May 18 2010 - 15:11:34 EST


Would you guys like to carry this patch, or should I push it up
-tip? If I don't hear otherwise from you, I will push it up -tip.
The INIT_RCU_HEAD() primitive is going away in favor of debugobjects.

Thanx, Paul


selinux: 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.
