docs: prevent warnings due to autosectionlabel
Changeset 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") enabled a new feature at Sphinx: it will now generate index for each document title, plus to each chapter inside it. There's a drawback, though: one document cannot have two sections with the same name anymore. A followup patch will change the logic of autosectionlabel to avoid most creating references for every single section title, but still we need to be able to reference the chapters inside a document. There are a few places where there are two chapters with the same name. This patch renames one of the chapters, in order to avoid symbol conflict within the same document. PS.: as I don't speach Chinese, I had some help from a friend (Wen Liu) at the Chinese translation for "publishing patches" for this document: Documentation/translations/zh_CN/process/5.Posting.rst Fixes: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") Signed-off-by: Mauro Carvalho Chehab <> Link: Signed-off-by: Jonathan Corbet <>
