svn commit: r193041 - head/sys/sys

[Edward Tomasz Napierala]

Author: trasz
Date: Fri May 29 15:00:04 2009
New Revision: 193041
URL: http://svn.freebsd.org/changeset/base/193041

Log:
  There is only one spare MNT_ flag left, and I want to use it for NFSv4 ACLs.
  Make room for additional filesystem flags now, to avoid breaking ABI later.
