[dm-devel] Re: [PATCH 0/2] dm-ioband: I/O bandwidth controller v1.8.0: Introduction

["Dong-Jae Kang" <baramsori72 gmail com>]

Hi, Ryo Tsuruta

I am trying to install your new released dm-ioband v1.8.0
I/O bandwidth controller v1.8.0 could be adjusted to  the latest
stable kernel 2.6.27.1
it was good news for me
but, I had a problem when I try to patch bio-cgroup files to  stable
kernel 2.6.27.1
many patch failure and hunk messages were occured.

Can you check bio-cgroup patch files against stable kernel 2.6.27.1?

If the dm-ioband and bio-cgroup patches had different base kernel, i
think it is not natural.
I think it is more reasonable to release dm-ioband and bio-cgroup
patches in pair.
In my situation, both direct IO and buffered IO are same important.

thank you

Regard,
Dong-Jae Kang
