It seems like megaraid doesn't have any reason to use delayed_work at
all.  It can use a plain work and cancel_work_sync() instead.  Maybe
it was doing the container_of() thing because workqueue didn't use to
have cancel_work_sync()?  Anyways, please convert it to use plain
work_struct post 3.7.

Thanks.
