[ Upstream commit174e7b1370] The 'rkey' input can be an lkey or rkey, and in rxe the lkey or rkey have the same value, including the variant bits. So, if mr->rkey is set, compare the invalidate key with it, otherwise compare with the mr->lkey. Since we already did a lookup on the non-varient bits to get this far, the check's only purpose is to confirm that the wqe has the correct variant bits.

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.
