Actually, given all of the recent problems here, I recommend taking some time off, and work with some more experienced kernel developers in your company first, to get the experience needed in order to properly submit kernel changes. I'd like to see at least one other mvista.com developer, who has such experience, sign off on your backports as well to get someone else to catch basic problems like this before the community is forced to do so. thanks, greg k-h
