I wonder whether designing-in a millisecond granularity is the right thing to do. If in a few years the kernel is running tickless with high-res clock interrupt sources, that might look a bit lumpy. Switching it to a __u64 nanosecond counter would be basically free on 64-bit machines, and not very expensive on 32-bit, no? - 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/ | ||||||||||||
