--- Comment #13 from Rick Macklem <rmacklem at FreeBSD.org> ---
A variant of the first patch has already been committed to head by mav at .
He also noted to me that the second patch isn't needed. The "else" case
doesn't have any other thread manipulating the list, so the thread mutex
isn't needed.

Since you are using NFSv4.1, I'm pretty sure that the third patch is the
one that fixes the problem. I will commit this to head soon and MFC it
before closing this PR. (Oh, and the NFSv4.1 server stuff isn't in stable/9,
so the fix only applies to 10 and head.)

Thanks for doing the testing, so this could get resolved.
