This series reworks all the places that execute commands to use a consistent
set of helpers around write(). The helpers are designed to accept the location
of all 5 buffers (hdr, cmd, drv_cmd, resp, drv_resp) involved with a command.

This cleanup removes a bunch of duplicated code and paves the way to add more
options for delivering commands to the kernel.

It is the same theme as the new uverbs kernel series currently on the list.

This is PR on github:

https://github.com/linux-rdma/rdma-core/pull/434

Jason Gunthorpe (10):
  verbs: Fix wrong command structure usage
