Refactor the restrack code to make sure the kref inside the restrack entry properly kref's the object in which it is embedded. This slight change is needed for future conversions of MR and QP which are refcounted before the release and kfree. The ideal flow from ib_core perspective as follows: * Allocate ib_* structure with rdma_zalloc_*. * Set everything that is known to ib_core to that newly created object. * Initialize kref with restrack help * Call to driver specific allocation functions. * Insert into restrack DB .... * Return and release restrack with restrack_put. Largely this means a rdma_restrack_new() should be called near allocating the containing structure.

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.
