http://perforce.freebsd.org/chv.cgi?CH=54389 Change 54389 by scottl@scottl-esp-sparc64 on 2004/06/08 03:16:23 For some unpleasant reason, giving an alignment arg of '8' to uma_zcreate() results in uma_zalloc() getting unaligned chunks. Add a basic implementation of XPT_PATH_INQ. The driver can now somewhat play with CAM.
