Jens Axboe d6de8be711 cfq-iosched: fix RCU problem in cfq_cic_lookup() ... cfq_cic_lookup() needs to properly protect ioc->ioc_data before dereferencing it and also exclude updaters of ioc->ioc_data as well. Also add a number of comments documenting why the existing RCU usage is OK. Thanks a lot to "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> for review and comments!
