Did you make any progress? Btw, I'd love if you could queue up the patch to use __smp_call_function_single directly in the block layer for 3.14. Independent of wether a llist using __smp_call_function_single is faster than one using the lock we get down from a list plus llist to just one of them, so I can't see how that patch will cause an issue. With all the prep patches already in it can be queue up independently of Jan's series as well. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
