====== Block I/O tracing ====== Ricardo and I developed a Linux kernel module to do tracing of block layer I/Os. I would appreciate if you can install this on your machine so we could collect traces as well as testing the module. I have been tracing my machine and doomsday for a couple of days now with no problems. This will only work for Ubuntu. I've only tested for 10.04 (my machine) and 8.04 (doomsday). You just have to download the script {{resources:install_tracing.sh}} and run it as root. If you find any problem, send me an email with the error .
