Only togreg seems to be in > next. Yup. That's intentional because I don't rebase the togreg branch unless something goes wrong when it hits next. The intent being it's a stable base to build upon. Normally there is a delay of up to a week to let 0-day take a look at testing and for me to happen to get time sat at the right computer, but sometimes it's longer :( Right now I'm waiting on a pull request being picked up by Greg KH, after which I'll fast forward the togreg branch as I have some patches waiting to be queued up that are dependent on things that have reached char-misc-next via other paths. Unfortunately I'm doubtful about whether I can squeeze in a second pull request this cycle, so they may get queued up for next cycle. A bit of bad timing :( Jonathan > > Best regards > Uwe >
