From 50ef0cdf58aea2f03f3d21390d68561ee7be215e Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 24 Jun 2019 01:13:27 +0900 Subject: [PATCH] kbuild: fix missed rebuild of modules.builtin Unlike modules.order, modules.builtin is not rebuilt every time. Once modules.builtin is created, it will not be updated until auto.conf or tristate.conf is changed. So, it does not notice a change in Makefile, for example, the rename of modules. Kbuild must always descend into directories for modules.builtin too.
