I might not be grasping the full context here, but I think the main script of kernel documentation tool ./scripts/kernel-doc (a perl script) changes its behavior depending on the target Sphinx version. Its help text says: > Output format modifiers > reStructuredText only > -sphinx-version VERSION > Use the ReST C domain dialect compatible with a specific Sphinx > Version. > > If not specified, kernel-doc will auto-detect using the > sphinx-build version found on PATH.

Yes, ".. c:namespace::" is actively used in userspace-api documentation. FYI, see a recent reply from Mauro WRT support of kernel documentation with different versions of Sphinx at: https://lore.kernel.org/linux-doc/20220521114629.6ee9fc06@xxxxxxxx/ Thanks, Akira > That would enable the kernel to gradually update > the syntax over a longer period, as I believe you won't be able to > use the v3 syntax currently. > > Equally, Jonathan said he was hesitant to increase the minimum to > Sphinx 3, so perhaps that wouldn't work. > > A
