rust: macros: vtable: fix
HAS_*
redefinition (gen_const_name
)
commit 3fa7187 upstream. If we define the same function name twice in a trait (using `#[cfg]`), the `vtable` macro will redefine its `gen_const_name`, e.g. this will define `HAS_BAR` twice: #[vtable] pub trait Foo { #[cfg(CONFIG_X)] fn bar(); #[cfg(not(CONFIG_X))] fn bar(x: usize); } Fixes: b44becc ("rust: macros: add `#[vtable]` proc macro") Signed-off-by: Qingsong Chen <changxian.cqs@antgroup.com> Reviewed-by: Andreas Hindborg <a.hindborg@samsung.com> Reviewed-by: Gary Guo <gary@garyguo.net> Reviewed-by: Sergio González Collado <sergio.collado@gmail.com> Link: https://lore.kernel.org/r/20230808025404.2053471-1-changxian.cqs@antgroup.com Signed-off-by: Miguel Ojeda <ojeda@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
