docs: sphinx-extensions: add metadata parallel-safe
The setup() function of a Sphinx-extension can return a dictionary. This is treated by Sphinx as metadata of the extension [1]. With metadata "parallel_read_safe = True" a extension is marked as save for "parallel reading of source". This is needed if you want build in parallel with N processes. E.g.: make SPHINXOPTS=-j4 htmldocs will no longer log warnings like: WARNING: the foobar extension does not declare if it is safe for parallel reading, assuming it isn't - please ask the extension author to check and make it explicit. Add metadata to extensions: * kernel-doc * flat-table * kernel-include [1] http://www.sphinx-doc.org/en/stable/extdev/#extension-metadataSigned-off-by: NMarkus Heiser <markus.heiser@darmarIT.de> Tested-by: NMauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: NJonathan Corbet <corbet@lwn.net>
