Ryo, this time you should get the mail. This is reply to my original reply. Also I wanted to test run your patches. How do I do that? I see that your patches are based on dm quilt tree. I downloaded the dm-patches and tried to apply on top of 2.6.30-rc1 but it failed. So can't apply your patches now. So what's the simplest way of testing your changes on latest kernels?
