I've applied. Note that I do like to get patches inline, for review purposes (and you can attach them also, if you are worried about mailers breaking something). Thanks also for including the commit hashes. I think the CLOCK_BOOTIME has should however be 70a08cca1227dc31c784ec930099a4417a06e7d0 and I amended accordingly.
