svn commit: r192861 - in head/sys/fs: nfs nfsserver

[Rick Macklem]

Author: rmacklem
Date: Tue May 26 22:21:53 2009
New Revision: 192861
URL: http://svn.freebsd.org/changeset/base/192861

Log:
  Fix the experimental nfs subsystem so that it builds with the
  current NFSv4 ACLs, as defined in sys/acl.h. It still needs a
  way to test a mount point for NFSv4 ACL support before it will
  work. Until then, the NFSHASNFS4ACL() macro just always returns 0.
