Use kunmap_local() to unmap pages locally mapped with kmap_local_page(). kunmap_local() must be called on the kernel virtual address returned by kmap_local_page(), differently from how we use kunmap() which instead expects the mapped page as its argument. In module_zstd_decompress() we currently map with kmap_local_page() and unmap with kunmap(). This breaks the code and so it should be fixed. [...]
Applied, thanks!
