Given that the subtree may have been in development for a long time, it is almost a certainty that the older commits may compile on A but not on C. By basing it all on C you create a lot of uncompilable commits which hurt bisection just as bad. At least with missing kernel sources it is obvious that an attempt at compilation is futile and a waste of 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/
