Self-NAKing this change. I wrote up some test code to help visualize how things were scheduled. That proved that the old function is pretty broken, but the new function not only has a typo (using "i" instead of "j" in a few places) but also suffers from some of the same problems as the old function. It might be easy to use the bitmap functions to implement this easily / properly. I'll see if I can do that. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
