svn commit: r249972 - in stable/9/sys/dev: hptmv mpt

New Revision: 249972
URL: http://svnweb.freebsd.org/changeset/base/249972

Log:
  MFC r249849:
  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.
