Subject: [PATCH] kbuild: rust: split up helpers.c
Date: Tue, 16 Apr 2024 09:46:07 +0200 [thread overview]
Message-ID: <20240416074607.1395481-1-nmi@metaspace.dk> (raw)
From: Andreas Hindborg <a.hindborg@samsung.com>
This patch splits up the rust helpers C file. When rebasing patch sets on
upstream linux, merge conflicts in helpers.c is common and time consuming
[1]. Thus, split the file so that each kernel component can live in a
separate file.
This patch lists helper files explicitly and thus conflicts in the file
list is still likely. However, they should be more simple to resolve than
the conflicts usually seen in helpers.c.
