Hi Alasdair, As you know, I have been developing a block I/O bandwidth controller on Linux. Now, I have almost finished implementation of the features and I think I have fixed all the points that you suggested. For the next step, I would like many people to use dm-ioband in various environments such as with a high-end storage, with a solid state drive and so, so that I will be able to get a lot of feedback from them to improve and enhance the controller. So, would you consider merging the dm-ioband patch into Linux kernel as one of device mapper modules? I think it is not hard to merge the code, because dm-ioband doesn't touch any existing code except Makefile and Kconfig files placed in drivers/md directory. You can get the patch from the following URL: http://people.valinux.co.jp/~ryov/dm-ioband/patches/dm-ioband-1.7.0.patch I would really appreciate it if you would reply me anything.
