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 proves this. It is your burden to even begin to substantiate _why_ both DM and MD are inadequate frameworks for virtual block device drivers. > > Baseless and unspecific assertions don't help your cause -- dm-thinp > > disproves your unconvincing position (manages it's metadata in kernel, > > etc). > > I'm not the only one who's read the dm code and found it lacking - and > anyways, I'm not really out to convince anyone. Like other kernel code, DM is approachable for those who are willing to put the time in to understand it.

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. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
