Revision:	1.2
Committed:	Tue Feb 18 23:23:36 2003 UTC (21 years, 2 months ago) by pajs
Content type:	text/plain
Branch:	MAIN
Changes since 1.1:	+2 -10 lines
Log Message:	Changed the kstat_close to not return NULL in event of a failure. If we cant close it, well there is nothing i can do about that, so i may as well at least return something useful since its done all the hardwork by that point. And anywan, it should never fail to close :)
