This fix looks right. I've compared the NFS code to the UFS code
as well as looked at the link() system call. The man page is wrong,
and the NFS code is wrong. I'll commit a fix to -4.x and after
getting the OK from Jordan, to -3.x too.
It also appears that nfs_rename() is broken ( it leaves namei data sitting
around, so no crash but...) And also possibly other nfs VOP calls -- I'll
have to audit all of them.
