There are too much magic inside docs Makefile to properly run sphinx-build. Create an ancillary script that contains all kernel-related sphinx-build call logic currently at Makefile. Such script is designed to work both as an standalone command and as part of a Makefile. As such, it properly handles POSIX jobserver used by GNU make. On a side note, there was a line number increase due to the conversion (ignoring comments) is: Documentation/Makefile | 131 +++---------- tools/docs/sphinx-build-wrapper | 293 +++++++++++++++++++++++++++++++ 2 files changed, 323 insertions(+), 101 deletions(-) Comments and descriptions adds: tools/docs/sphinx-build-wrapper | 261 +++++++++++++++++++++++++++++++- So, about half of the script are comments/descriptions. This is because some things are more verbosed on Python and because it requires reading env vars from Makefile. Besides it, this script has some extra features that don't exist at the Makefile: - It can be called directly from command line; - It properly return PDF build errors. When running the script alone, it will only take handle sphinx-build targets. On other words, it won't runn make rustdoc after building htmlfiles, nor it will run the extra check scripts.

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 reStructuredText 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.
