Yes, it's all a bit mysterious. I just look in the changelog, which was pull edout of the git diff via various means. See how ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.25-rc5/2.6.25-rc5-mm1/broken-out starts with 5813a19cba5735b629cdeb156863dab814759128 and ends with 816543f9bf2fb77ff52083216a4537eb4e3058ec. Use 5813a19cba5735b629cdeb156863dab814759128 as good and 816543f9bf2fb77ff52083216a4537eb4e3058ec as bad. -- 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/
