From: Miguel Ojeda Date: Sat, 3 Jul 2021 15:18:23 +0000 (+0200) Subject: rust: export generated symbols X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=296e421767f3c320b9c614faef7904174db77a93;p=users%2Fjedix%2Flinux-maple.git rust: export generated symbols All symbols are reexported reusing the `EXPORT_SYMBOL_GPL` macro from C. The lists of symbols are generated on the fly. There are three main sets of symbols to distinguish: - The ones from the `core` and `alloc` crates (from the Rust standard library). The code is licensed as Apache/MIT. - The ones from our abstractions in the `kernel` crate. - The helpers (already exported since they are not generated). We export everything as GPL. This ensures we do not mistakenly expose GPL kernel symbols/features as non-GPL, even indirectly.
