Btrfs devel - Sep 2014 - [PATCH v3 0/2] Move BTRFS RCU string to common library

This patch series makes the generic RCU string library used internally by BTRFS
accessible by anyone.

The first patch makes printk_ratelimited pass on the return value from printk.
Version 3 gives the temporary return variable a unique name to avoid name
clashes.

The second patch moves the RCU string header and updates the BTRFS code that
depends on it. Version 3 adds the __rcu annotation to the relevant functions.

Version 3 also adds Paul's ack and Josh's review.
