We have quite a lot of code that illustrates how to implement DM
targets. DM isn't forcing undue or cumbersome constraints that prevent
it's use for complex targets with in-kernel metadata -- again dm-thinp
It is your burden to even begin to substantiate _why_ both DM and MD are
inadequate frameworks for virtual block device drivers.

Like other kernel code, DM is approachable for those who are willing to
put the time in to understand it. Your hand-waving (and now proxy)
critiques leave us nothing to work with.

Say what? Nice projection. Luckily the thread is public for all to see.
I initially thought Christoph's feedback in this thread was harsh; now
it seems eerily prophetic.
Lets stop wasting our time on this thread. Maybe we can be more
constructive in the future.
