He did a good job of isolating the problem which was caused by the new NFS client not setting the post write mtime correctly. The new NFS client code was cloned from the old client, but was incorrect, because the mtime in the nfs vnode's cache wasn't yet updated. This patch fixes this problem. The patch also adds missing mutex locking. END
