One big problem of the commit is that it is basically a serialized workqueue
because of single &hctx->run_work, and per-req work_struct has to be
used for concurrent implementation. So looks the approach isn't flexible
enough compared with doing that in driver, or any idea about how to fix
that?
Thanks
