The IB_WR_REG_MR and IB_WR_LOCAL_INV operations for smbdirect_mr_io structures should never fail because the submission or completion queues are too small. So we allocate more send_wr depending on the (local) max number of MRs. While there also add additional space for ib_drain_qp(). This should make sure ib_post_send() will never fail because the submission queue is full.

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 reStructuredText 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.
