cfq-iosched: add hlist for browsing parallel to the radix tree It's cumbersome to browse a radix tree from start to finish, especially since we modify keys when a process exits. So add a hlist for the single purpose of browsing over all known cfq_io_contexts, used for exit, io prio change, etc. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=9948 Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

cfq-iosched: fix RCU race in the cfq io_context destructor handling put_io_context() drops the RCU read lock before calling into cfq_dtor(), however we need to hold off freeing there before grabbing and dereferencing the first object on the list. So extend the rcu_read_lock() scope to cover the calling of cfq_dtor(), and optimize cfq_free_io_context() to use a new variant for call_for_each_cic() that assumes the RCU read lock is already held.
