32 is too many for the likes of kbl, and in order to insert that many requests into the ring requires us to declare the first few hung -- understandably a slow and unexpected process. Instead, measure the size of a singe requests and use that to estimate the upper bound on the chain length we can use for our test, remembering to flush the previous chain between tests for safety.

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.
