svn commit: r267191 - head/sys/fs/nfsserver

[Rick Macklem]

Author: rmacklem

New Revision: 267191
URL: http://svnweb.freebsd.org/changeset/base/267191

Log:
  The new NFS server would not allow a hard link to be
  created to a symlink. This restriction (which was
  inherited from OpenBSD) is not required by the NFS RFCs.
  Since this is allowed by the old NFS server, it is a
  POLA violation to not allow it. This patch modifies the
  new NFS server to allow this.
