Author: mav Date: Wed Apr 24 19:00:45 2013 New Revision: 249849 URL: http://svnweb.freebsd.org/changeset/base/249849 Log: Move hptmv and mpt drivers shutdown a bit later to the SHUTDOWN_PRI_LAST stage of shutdown_post_sync. That should allow CAM to do final cache flush at the SHUTDOWN_PRI_DEFAULT without using polling magic.
