svn commit: r259771 - head/sys/fs/nfsclient

[Rick Macklem]

Author: rmacklem
Date: Mon Dec 23 15:16:53 2013
New Revision: 259771
URL: http://svnweb.freebsd.org/changeset/base/259771

Log:
  The NFSv4.1 client didn't return NFSv4.1 specific error codes
  for the Getattr and Recall callbacks. This patch fixes it.
  Since the NFSv4.1 specific error codes would only happen for
  abnormal circumstances, this patch has little effect, in practice.
