Hello,
It might be better to put this patch at the end rather than in the
middle so that when this patch is applied things are actually fixed.

(cc'ing Greg)
Greg, block layer switches association between backing_device_info and
its struct device and needs to protect it with RCU. Yufen did so by
introducing a wrapping struct around struct device like above. Do you
think it'd make sense to just embed rcu_head into struct device and
let put_device() to RCU release by default?
Thanks.
