New Revision: 194449
URL: http://svn.freebsd.org/changeset/base/194449
Log:
Import newer versions of these files from a 20080410 checkout of
OpenSolaris. Our local diffs to these files in HEAD already contain all
these changes (and in fact seem to be based on these versions of the files).
It seems the vendor branch just has older versions somehow.
