Where is the dm-vdo `dmsetup create foo --table ...` documentation? #43

Hello,

I would like to understand the low-level behavior of VDO at the target level. Where is the vdo target's dmsetup create and dmsetup message documentation?

I've looked around, usually there is a dm-<target>.txt or similar document (like Documentation/device-mapper/cache.txt in the kernel tree) that defines all of the device-mapper table options, but I couldn't find anything informative when grepping these "vdo" and "kvdo" GIT trees for dmsetup.*create and the like.

Is there such a document? If not, where does kvdo parse the table arguments in your kernel module?

Thanks for your help!

-Eric

Hi Eric; I apologize for the delay in replying, I was hoping that we could get the relevant documentation pushed to the unstable branch on Friday but it didn't happen; we should get this doc pushed there soon. In the meantime, here's our work-in-progress dm-vdo.rst documenting the table line.

Awesome, thanks! I'll let you close this in case you want it open until it pushes upstream.
