From 876346536c1b59a5b1b5e44477b1b3ece77647fd Mon Sep 17 00:00:00 2001 From: Andreas Hindborg Date: Thu, 15 Aug 2024 10:30:26 +0000 Subject: rust: kbuild: split up helpers.c 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. [ Removed `README.md` and undeleted the original comment since now, in v3 of the series, we have a `helpers.c` again; which also allows us to keep the "Sorted alphabetically" line and makes the diff easier. In addition, updated the Documentation/ mentions of the file, reworded title and removed blank lines at the end of `page.c`. - Miguel ] Link: https://rust-for-linux.zulipchat.com/#narrow/stream/288089-General/topic/Splitting.20up.20helpers.2Ec/near/426694012 [1] Signed-off-by: Andreas Hindborg Reviewed-by: Gary Guo Acked-by: Dirk Behme Reviewed-by: Alice Ryhl Reviewed-by: Benno Lossin Link: https://lore.kernel.org/r/20240815103016.2771842-1-nmi@metaspace.dk Signed-off-by: Miguel Ojeda --- rust/helpers/build_bug.c | 10 ++++++++++ 1 file changed, 10 insertions(+) create mode 100644 rust/helpers/build_bug.c (limited to 'rust/helpers/build_bug.c') diff --git a/rust/helpers/build_bug.c b/rust/helpers/build_bug.c new file mode 100644 index 000000000000..f3106f248485 --- /dev/null +++ b/rust/helpers/build_bug.c @@ -0,0 +1,10 @@ +// SPDX-License-Identifier: GPL-2.0 + +#include +#include + +const char *rust_helper_errname(int err) +{ + return errname(err); +} +EXPORT_SYMBOL_GPL(rust_helper_errname); -- cgit From e26fa546042add70944d018b930530d16b3cf626 Mon Sep 17 00:00:00 2001 From: Gary Guo Date: Sat, 17 Aug 2024 17:51:32 +0100 Subject: rust: kbuild: auto generate helper exports This removes the need to explicitly export all symbols. Generate helper exports similarly to what's currently done for Rust crates. These helpers are exclusively called from within Rust code and therefore can be treated similar as other Rust symbols.
