--- Comment #7 from Alan Somers <asomers@FreeBSD.org> ---
Those are the expected file descriptors.  What we don't see is any open zvo=
ls.=20
And since zfsd doesn't change any in-kernel state, I really don't see any w=
ay
that it could interfere with the VM.  Unless you can come up with steps to
reproduce starting from a clean system, I don't think it would be productiv=
e to
investigate zfsd any more.

In what sense does it "seems to be impossible"?  What kind of error do you =
get
when you try this?
