DDB patches

[Dan Partelly]

 Hey Pedro,

some times ago you got some DDB patches from me in which I added relational ops support from it. The patch was a bit clobbered, 
but last I know you cleaned it up and put it somewhere on freebsd.org (prolly your page) up for review. 

Could you or Adrian review the patch set , and if it is OK potentially proceed with a commit ? Or if it is not ok for a commit , please advice on a follow up. 

Thanks you guys .
