It now has a probe for every operation, both regular and callback, client and server. A few new fields have been added to args[0], which I hope will be useful. It''s not done yet, so there''s still time to make improvements. I''d really like to get some feedback on this -- please email either dtrace-discuss at opensolaris.org or me directly. Thanks! - Sam
