should be \"%s\" I guess - will fix that and the other findings - just waiting for feedback if it makes any sense at all to include something like this. > Otherwise, as a semantic patch, it looks fine.

I'm not aware of any case in the kernel where the passing of a jiffies value is intentionally HZ dependent - so I guess atleast warning on this makes sense. Anyway it might also make more sense to put something like this into one of the build-bots rather than push it into mainline for general use. thx! hofrat -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
