Auto merge of #126761 - GuillaumeGomez:unsafe_extern_blocks, r=spasto…
…rino rustdoc: Add support for `missing_unsafe_on_extern` feature Follow-up of #124482. Not sure if the `safe` keyword is supposed to be displayed or not though? For now I didn't add it in the generated doc, only `unsafe` as usual. cc `@spastorino` r? `@fmease`
