Linux kernel source tree

Inside schedule_out, we do extra work upon idling the context, such as updating the runtime, kicking off retires, kicking virtual engines. However, if we are in a series of processing single requests per contexts, we may find ourselves scheduling out the context, only to immediately schedule it back in during dequeue. This is just extra work that we can avoid if we keep the context marked as inflight across the dequeue. This becomes more significant later on for minimising virtual engine misses.

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.
