[PATCH 0/9] Second round of v4.17 NFS/RDMA client patches

[Chuck Lever <chuck.lever@oracle.com>]

Hi Anna-

Second round of three. This set could be more controversial. In it,
I adjust some code paths so that I can create rpcrdma-specific
alloc_slot and free_slot methods. These are clean-ups that make
it straightforward to do the changes coming in the third round,
and hopefully add a little bit of a scalability boost as well.
