Description Andrey Konovalov 2023-12-25 17:44:48 UTC 
Currently, KASAN uses EXPORT_SYMBOL_GPL to mark the symbols that are only exported to allow building KASAN tests as a module.

We can instead create a separate namespace for these symbols and use EXPORT_SYMBOL_NS.

This would work as a guard against external code accidentally using KASAN-internal symbols.
Comment 1 Andrey Konovalov 2024-10-23 08:41:17 UTC 
Instead of creating a separate namespace, we can reuse EXPORT_SYMBOL_IF_KUNIT.
