Thomas,
To my knowledge, 'ptlrpcd' is a thread that's responsible for pushing
asynchronous rpc requests to various places. It is also tasked with
receiving the replies to those requests.
I imagine the OSS has a lot of outstanding async rpc's which need to be
continually processed. It's just a hunch.. I haven't dug around in the
OSS enough to know exactly what's going on.
