[PATCH 0/2] dm-band: The I/O bandwidth controller: Overview
Hi everyone, I'm happy to announce that I've implemented a Block I/O bandwidth controller. The controller is designed to be of use in a cgroup or virtual machine environment. The current approach is that the controller is implemented as a device-mapper driver. What's dm-band all about? ======================== Dm-band is an I/O bandwidth controller implemented as a device-mapper
