If you're feeling motivated, maybe you can narrow it down to which of the changes - xfs_highbit32, xfs_highbit64, xfs_lowbit32, or xfs_lowbit64 - is causing the problem? (or maybe they all are ...) Or maybe someone looking at the commit can immediately see the problem... but I can't :) -Eric -- 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/
