any reason why only suse has this, but not mainline ?

i came across that module in suse kernel just some days ago and asked novell ( https://bugzilla.novell.com/show_bug.cgi?id=396132 ) , but they don`t have any objections.
chris mason didn`t reply on direct request....

so, if it`s useful, who is reponsible for pushing it upstream ?
