New Revision: 255551
URL: http://svnweb.freebsd.org/changeset/base/255551

Log:
  MFC r249194 (by trasz):
  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.
