The solution to this situation, as I understand it (on Linux), is TASK_KILLABLE, which effectively supercedes uninterruptible sleep as a concept: https://lwn.net/Articles/288056/

But TASK_KILLABLE is not used in most places it should be. Patching your (least) favorite driver to use TASK_KILLABLE could be a good entry point to contributing to the kernel.
