What are the units of this? microseconds? jiffies? seconds? At the least, the covering comment should make clear what units this variable is using. Better would be to actually embed the units in the variable's identifier. Because it's awfulyl easy to make mistakes over this, and not knowing the units makes the code harder to follow. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
