At a glance, it looks to me like 8.x is affected. Note that the
bug only affects the new NFS server (the experimental one for 8.x)
when exporting ZFS volumes. (UFS exported volumes don't leak)
If you are running a server that might be affected, just:
# vmstat -z | fgrep -i namei
on the server and see if the 3rd number shown is increasing.
