If you wanna split it further or do it your way, please feel free to. I think it would be beneficial to do things now but, hey, you guys are maintaining dm part of the kernel, so it's up to you guys. But, I think it would be silly for everyone else to wait for the rather special requirement for dm, so if we have to go forward without dm updates, I suppose we will have to. Jens, please feel free to drop dm conversion patches. Thanks. -- tejun
