Author: rmacklem Date: Thu Jul 7 00:14:20 2011 New Revision: 223829 URL: http://svn.freebsd.org/changeset/base/223829 Log: MFC: r223436 Fix the new NFSv4 client so that it uses the same uid as was used for doing a mount when performing system operations on AUTH_SYS mounts. This resolved an issue when mounting a Linux server. Found during testing at the recent NFSv4 interoperability Bakeathon.
