Israel Rukshin f41725bbe1 nvme-rdma: Use mr pool
Currently, blk_mq_tagset_iter() iterate over initial hctx tags only.  If
an I/O scheduler is used, it doesn't iterate the hctx scheduler tags and
the static request aren't been updated. For example, while using NVMe
over Fabrics RDMA host, this cause us not to reinit the scheduler
requests and thus not re-register all the memory regions during the
tagset re-initialization in the reconnect flow.

This may lead to a memory registration error:

  "MEMREG for CQE 0xffff88044c14dce8 failed with status memory management operation error (6)"

With this commit we don't need to reinit the requests, and thus fix this
failure.

README

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.
