[OmniOS-discuss] l2arc 16.0E accounting leak

[wuffers]

First of all, thanks to all the hard work of everyone involved in the
community edition. I will most likely go from r151022 to the latest when I
get a chance to have scheduled maintenance.

I hadn't seen a reply to this, so not sure if it has already been resolved,
or it's just my installation that's seeing the issue. Is anyone else using
l2arc without this issue?
