Sure, that's fine.

I was really just suggesting to put:

+# test that we have DMAPI support
+_dmapi_scratch_mount
+unmount $SCRATCH_MNT > /dev/null 2>&1

directly into common.dmapi - not as a function
but just as code to always execute.
As long as there is no output under normal circumstances from
this, then all dmapi tests should not require any change
and it is simpler (all they need is to include common.dmapi
which most do).
There may be an extra mount in some of the
tests (for those that want to keep it mounted) but who cares.
Why include common.dmapi if you don't require it to be supported :)
