Since commit cdd30ebb1b9f ("module: Convert symbol namespace to string literal"), exported symbols marked by EXPORT_SYMBOL_NS(_GPL) are ignored by "kernel-doc -export" in fresh build of "make htmldocs". This is because regex in the perl script for those markers fails to match the new signatures: - EXPORT_SYMBOL_NS(symbol, "ns"); - EXPORT_SYMBOL_NS_GPL(symbol, "ns"); Update the regex so that it matches quoted string. Note: Escape sequence of \w is good for C identifiers, but can be too strict for quoted strings. Instead, use \S, which matches any non-whitespace character, for compatibility with possible extension of namespace convention in the future [1].

Quick reproducer: ./script/kernel-doc -rst -export drivers/iommu/iommufd/device.c On v6.13-rc2, kernel-doc will say: drivers/iommu/iommufd/device.c:1: warning: no structured comments found With this patch applied, you'll get reST formatted kernel-doc comments.
