Hi Kostik,

I'm afraid there was a reason that only certain cases (where the file was
being shrunk) did the vnode_pager_setsize() call after the NFS node
lock is released.

See the commit log message for r252528.

If vnode_pager_setsize() now acquires a sleep lock for the case where the
size is increasing, it sounds like the NFS node lock will have to become a
sleep lock instead of a mutex.
(If needed, I can get working on this in a day or two.)
