As a workaround to make the documentation build again (but known that parts of the documentation will be broken), we could drop the cdomain extension. Regards, Salvatore >From 9e81028c7e5f8f33f67a768b9c306536fd8e688f Mon Sep 17 00:00:00 2001 From: Salvatore Bonaccorso <car...@debian.org> Date: Wed, 12 Aug 2020 09:11:51 +0200 Subject: [PATCH] Documentation: Drop use of 'cdomain' sphinx extension module 'c_funcptr_sig_re' was removed upstream in sphinx v3.0.0b1 and so the kernel documentation build fails sphinx 3.x. As a (temporary) workaround to make the documentation build, the 'cdomain' sphinx extension can be removed from the Documentation build configuration file, although some parts using the feature will be broken. https://github.com/sphinx-doc/sphinx/issues/7421 describes the workaround.
