Describe the problem you're observing

Without -v, zpool -o obeys the request:
$ zpool list -o name,frag NAME FRAG zfs 70%

But with -v, -o is ignored for per-vdev stats. It looks like default fields are shown despite what I wrote in -o.

NAME FRAG zfs 70% vdc 128G 85.9G 41.1G - - 70% 67.6% - ONLINE special - - - - - - - - - vdd 1014M 112M 848M - - 51% 11.7% - ONLINE

Describe how to reproduce the problem

Run with -v and -o
