Description

We want to implement general ptlrpcd pool, the ptlrpcd threads in such pool are shared by all the async RPCs on the client, like BRW request, data checksum, async glimpse lock, statahead, and so on.

Current idea is one ptlrpcd thread per CPU-core (or partition), and bind ptlrpcd thread on the CPU-core.
