(if > yes, what type of dependencies?) The big problem is that nobody actually knows where all the dependancies are. That is why I've started with the bits we can decipher so that it simplifies the mess each time we clean up the locking of some lower level aspect. Almost all the serial drivers clone the same open and release methods (or worse older versions of it) so that also needs doing. Lots to do, so little time. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
