Subject: [for-next][PATCH 2/2] rust: jump_label: skip formatting generated file
From: Miguel Ojeda <ojeda@...nel.org>
After a source tree build of the kernel, and having used the `RSCPP`
rule, running `rustfmt` fails with:
error: macros that expand to items must be delimited with braces or followed by a semicolon
--> rust/kernel/arch_static_branch_asm.rs:1:27
|
1 | ...ls!("1: jmp " ... ".popsection \n\t")
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
help: change the delimiters to curly braces
|
1 | ::kernel::concat_literals!{"1: jmp " ... ".popsection \n\t"}
| ~ ~
help: add a semicolon
|
1 | ::kernel::concat_literals!("1: jmp " ... ".popsection \n\t");
| +
This file is not meant to be formatted nor works on its own since it is
meant to be textually included.
Thus skip formatting it by prefixing its name with `generated_`.
