Current implementation was not properly handling frwr memory
registrations. This was uncovered by commit 27f26cec761das ("xprtrdma:
Plant XID in on-the-wire RDMA offset (FRWR)") in which xprtrdma, which is
used for NFS over RDMA, started failing as it was the first ULP to modify
the ib_mr iova resulting in the NFS server getting REMOTE ACCESS ERROR
when attempting to perform RDMA Writes to the client.
The fix is to properly capture the true iova, offset, and length in the
call to ib_map_mr_sg, and then update the iova when processing the
IB_WR_REG_MEM on the send queue.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
