I was going to hack LB a bit, and add a timestamp, just like you see in the newer Linux kernels, to look for potential bottlenecks specific to my MLB. The kernel printk uses sched_clock() to get the current time. Is there an equivalent call in LB? I've looked through the code base for files / code that has *clock* or *time* or something similar, but without much luck.
There used to be something like POST_TSC which prints the CPU TSC register value in every printk. I don't know if it is still there.
