<linux/export.h> is the right header to include for using EXPORT_SYMBOL_GPL. <linux/module.h> includes much more bloat.

/*
|
|
* A hack to export Rust symbols for loadable modules without having to redo
|
|
* the entire `include/linux/export.h` logic in Rust.
|
|
*
|
|
* This requires the Rust's new/future `v0` mangling scheme because the default
|
|
* one ("legacy") uses invalid characters for C identifiers (thus we cannot use
|
|
* the `EXPORT_SYMBOL_*` macros).
|
|
*
|
|
* All symbols are exported as GPL-only to guarantee no GPL-only feature is
|
|
* accidentally exposed.
