[linux-lvm] raidintegrity on non top level LVs

[ajs124]

Hi,

I've been wondering. Why does lvconvert not allow me to add raid
integrity to LVs that are not top level?
It only says "Integrity can only be added to top level raid LV."

Skimming the commit that added this [1] did not provide me with
an answer, so I thought I'd ask here.

Best Regards
