svn commit: r249194 - head/sys/cam/ctl

[Edward Tomasz Napierala]

Author: trasz
Date: Sat Apr  6 10:34:02 2013
New Revision: 249194
URL: http://svnweb.freebsd.org/changeset/base/249194

Log:
  Make SYNCHRONIZE CACHE work with LUNs backed by device files (as opposed
  to regular files, which already worked fine).  With this change, it's no
  longer neccessary to use "ctladm realsync off" workaround.
