From 325eba05e8ab53a9182a2734f0986c15e5f87349 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 1 May 2022 17:40:10 +0900 Subject: modpost: traverse modules in order Currently, modpost manages modules in a singly linked list; it adds a new node to the head, and traverses the list from new to old. It works, but the error messages are shown in the reverse order. If you have a Makefile like this: obj-m += foo.o bar.o then, modpost shows error messages in bar.o, foo.o, in this order. Use a doubly linked list to keep the order in modules.order; use list_add_tail() for the node addition and list_for_each_entry() for the list traverse. Now that the kernel's list macros have been imported to modpost, I will use them actively going forward.
