Subject: [net-next-2.6 00/10] caif: rcu, refactoring and bugfixes

This patch-set introduces RCU in the CAIF stack and
fixes problems found when removing CAIF Link layer during traffic.

The pattern used for RCU is mostly this:
	rcu_read_lock();
	p = get();
	hold(p);
	rcu_read_unlock();
	use(p);
	put(p);

And when freeing:
	synchronize_rcu();
	wait_refcnt(p);
	kfree(p);

Sjur Brændeland (10):
  caif: Use rcu_read_lock in CAIF mux layer.
  caif: Use RCU instead of spin-lock in caif_dev.c
  caif: Use RCU and lists in cfcnfg.c for managing caif link layers
  caif: Add ref-count to framing layer
  caif: Move refcount from service layer to sock and dev.
  caif: Protected in-flight packets using dev or sock refcont.
  caif: prepare support for namespaces
  caif: Handle dev_queue_xmit errors.
  caif: Bugfix debugfs directory name must be unique.
  caif: remove unesesarry exports
