Description cryx-freebsd 2015-02-19 13:53:22 UTC 
When trying to do a "zfs list -t bookmark" on a zvol I get the error message "operation not applicable to datasets of this type".

# zfs list -o name,type data/zvol
NAME       TYPE
data/zvol  volume
# zfs list -t bookmark -r data/zvol
cannot open 'data/zvol': operation not applicable to datasets of this type

Doing the same with snapshot does work:

# zfs list -t snapshot -r data/zvol
NAME                         USED  AVAIL  REFER  MOUNTPOINT
data/zvol@snapshot          12.8K      -  1.15M  -

Doing it with snapshot and bookmark does work also:

# zfs list -t bookmark,snapshot -r data/zvol
NAME                         USED  AVAIL  REFER  MOUNTPOINT
data/zvol@snapshot          12.8K      -  1.15M  -
data/zvol#bookmark              -      -      -  -

(In reply to cryx-freebsd from comment #1)

this problem still exists in freebsd 12.0-release.
did any freebsd devs get back to you regarding this? seems your fix is very simple.
Comment 3 cryx-freebsd 2019-04-02 07:10:00 UTC 
No I've got no feedback at all. And you are right, this still exists in 12.0-RELEASE.

  Allow ZVOL bookmarks to be listed recursively

  Many thanks to cryx-freebsd@h3q.com for reporting the problem and
  submitting a fix.  I have chosen to take an equivalent but textually
  different patch from ZoL just to avoid increasing divergence between
  OpenZFS flavours.
