[PATCH master] turn on swap flag

[Joel Granados Moreno <jgranado redhat com>]

Hello list.

I'm going to give this patch to the reported for testing.  But it seems
like something we should be doing.  Don't know if its worth while to
make mkswap check and activate this flag.

Comments appreciated.

Regards.
