Subject: [PATCH] selinux: remove all rcu head initializations
Date: Tue, 18 May 2010 12:11:25 -0700	[thread overview]
Message-ID: <20100518191125.GA7014@linux.vnet.ibm.com> (raw)

Hello!

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.
