The approach of serializing buffer/map cleanup against device teardown using a mutex on `fastrpc_session_ctx` is directionally reasonable, but the implementation has **critical bugs** that would prevent compilation and introduce resource leaks. The patch should not be applied in its current form. --- Generated by Claude Code Patch Reviewer
