Bonded request submission is designed to allow requests to execute in parallel as laid out by the user. If the master request is already finished before its bonded pair is submitted, the pair were not destined to run in parallel and we lose the information about the master engine to dictate selection of the secondary. If the second request was required to be run on a particular engine in a virtual set, that should have been specified, rather than left to the whims of a random unconnected requests! In the selftest, I made the mistake of not ensuring the master would overlap with its bonded pairs, meaning that it could indeed complete before we submitted the bonds. Those bonds were then free to select any available engine in their virtual set, and not the one expected by the test.

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.
