svn commit: r249849 - in head/sys/dev: hptmv mpt

[Alexander Motin]

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.
