[PATCH v1 00/18] NFS/RDMA client patches for 4.7

[Chuck Lever <chuck.lever-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

One larger change: Attempt to fence memory regions after a signal
interrupts a synchronous RPC. This should prevent a server from
writing a reply into a client's memory after the memory has been
released.

In addition, the following changes and fixes:

- Use new ib_drain_qp() API
- Advertise max size of NFSv4.1 callbacks on RPC/RDMA
- Prevent overflowing the server's receive buffers
- Read list + Reply chunk (to support krb5i and krbp on RPC/RDMA)
- Detect connection loss sooner
