Hello, Month's ago, I posted a message to this list asking whether Red Hat had any plans for including the on-demand timer patch into their 390 kernel. At the time, the answer was no due to a lack of perceived interest. However, my boss reports that at SHARE every linux/390 performance related workshop listed taming the jiffies problem as the number one tuning priority, so there is some interest out there. Although I hate to repeat myself, I have to ask once again...does RH plan on including the on demand timer patch into their 390 kernel? Michael Lambert
