Apologies - I jumped to conclusions in my original bug report After applying your patch and seeing it did not fix the issue, I did a bit of investigation myself. It turns out the problem wasn't in the linked commit, but actually part of the upstream kernel: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.11&id=596b0474d3d9b1242eab713f84d8873f9887d980
The real problem isn't in the code however, but in my Makefile. I didn't run the "modules_prepare" target before trying to build a module, despite it being documented: https://www.kernel.org/doc/Documentation/kbuild/modules.txt Adding that target to my Makefile resolved the issue, without any changes to the linux-source package.
