The patch has lived in my public tree for a few days now and the kbuild bot 
hasn't complained (or rather it complained on the previous version that I 
hadn't posted to the list yet, and I've fixed the problems before posting this 
version). Given the risk of conflicts I'd rather get this merged sooner than 
later. Is that fine with you ?
