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.

If command prep fails, current handling will orphan subsequent requests in the list. Consider a simple example: rqlist = [ 1 -> 2 ] When prep for request '1' fails, it will be appended to the 'requeue_list', leaving request '2' disconnected from the original rqlist and no longer tracked. Meanwhile, rqlist is still pointing to the failed request '1' and will attempt to submit the unprepped command. Fix this by updating the rqlist accordingly using the request list helper functions.
