svc_rdma_rw.c already contains helpers for the sendto path. Introduce helpers for the recvfrom path. The plan is to replace the local NFSD bespoke code that constructs and posts RDMA Read Work Requests with calls to the rdma_rw API. This shares code with other RDMA-enabled ULPs that manages the gory details of buffer registration and posting Work Requests. This new code also puts all RDMA_NOMSG-specific logic in one place. Lastly, the use of rqstp->rq_arg.pages is deprecated in favor of using rqstp->rq_pages directly, for clarity. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
