I thought I was kind of am ;-) .

Good point I will put it on my list of things to do. Meanwhile can
I help you with the immediate problem of the tagging? could you do
something most brutal that even removes the tag support, just to
get you going?

And speaking of osdblk. Should it be its own full blown driver
or should it be under dm ? I know that at some LSF people said
it is better placed there? Specially since for a long time I wanted
to base it over ORE and not directly libosd so to support
RAID0/1/5/6 under the one simple block device.

Yes exactly that!
I wish I could have the time, perhaps one day I will. There is so much
more cleaning I can see.

Thanks Christoph
