From 1d082773ff30e97c8bc10b65c4aa0d073664caac Mon Sep 17 00:00:00 2001 From: Matthias Maennich Date: Fri, 6 Sep 2019 11:32:31 +0100 Subject: modpost: add support for generating namespace dependencies This patch adds an option to modpost to generate a .ns_deps file per module, containing the namespace dependencies for that module. E.g. if the linked module my-module.ko would depend on the symbol myfunc.MY_NS in the namespace MY_NS, the my-module.ns_deps file created by modpost would contain the entry MY_NS to express the namespace dependency of my-module imposed by using the symbol myfunc. These files can subsequently be used by static analysis tools (like coccinelle scripts) to address issues with missing namespace imports. A later patch of this series will introduce such a script 'nsdeps' and a corresponding make target to automatically add missing MODULE_IMPORT_NS() definitions to the module's sources. For that it uses the information provided in the generated .ns_deps files.
