2024-11-12samples: rust: fix `rust_print` build making it a combined moduleMiguel Ojeda1-1/+3
The `rust_print` module, when built as a module, fails to build with: ERROR: modpost: missing MODULE_LICENSE() in samples/rust/rust_print_events.o ERROR: modpost: "__tracepoint_rust_sample_loaded" [samples/rust/rust_print.ko] undefined! ERROR: modpost: "rust_do_trace_rust_sample_loaded" [samples/rust/rust_print.ko] undefined! Fix it by building it as a combined one.

2024-11-04rust: samples: add tracepoint to Rust sampleAlice Ryhl1-1/+2
This updates the Rust printing sample to invoke a tracepoint. This ensures that we have a user in-tree from the get-go even though the patch is being merged before its real user.

2022-09-28samples: add first Rust examplesMiguel Ojeda1-0/+5
The beginning of a set of Rust modules that showcase how Rust modules look like and how to use the abstracted kernel features. It also includes an example of a Rust host program with several modules. These samples also double as tests in the CI.
