Hi Vivek,

> Applying patch dm-add-request-based-facility.patch

"dm-add-request-based-facility.patch" is not my patch. To apply my
patch, you need to edit the series file and comment out the patch
files after "mm" section and my patch like this:

  ############################################################
  # Marker corresponding to end of -mm tree.
  ############################################################

  #dm-table-fix-alignment-to-hw_sector.patch
  mm

  # An attempt to get UML to work with dm.
  uml-fixes.patch

  ############################################################
  # May need more work or testing, but close to being ready.
  ############################################################

  # Under review
  #dm-exception-store-generalize-table-args.patch
  #dm-snapshot-new-ctr-table-format.patch
  #dm-snapshot-cleanup.patch

  #dm-raid1-add-clustering.patch
  dm-add-ioband.patch

And then type "quilt push dm-add-ioband.patch" command.
However, the patch can be applied, but a compile error is caused
because the patch is against the previous dm-tree.

> So what's the simplest way of testing your changes on latest kernels?

So I've uploaded a patch against 2.6.30-rc1. Please use it if you
like. http://people.valinux.co.jp/~ryov/dm-ioband/
The bio-cgroup patch against 2.6.30-rc1 will be uploaded within a few
days. I'm looking forward to your feedback on dm-ioband.

Thanks,
Ryo Tsuruta
