New Revision: 256638
URL: http://svnweb.freebsd.org/changeset/base/256638
Log:
Add cases for the combinations of busdma sync op flags that we handle
correctly by doing nothing, then add a panic for the default case, because
that implies that some driver asked for a sync (probably incorrectly) and
nothing was done.
