So the -rc2's have lately been pretty small - looking more like late -rc's than early ones. It *used* to be that I couldn't even post the shortlog, because it was just too big. That's not been the case for the last few releases.
I think people tend to take a breather after the merge window, because the -rc3's tend to then be a bit bigger again. But it may just also be that I've just gotten much better at saying "the merge window is over, I'm not taking random stragglers", or that people are just getting better at keeping to the merge window. Whatever the reason, the time of huge -rc2's seems to be happily behind us.
So in the 4.1 development cycle we match that new pattern. Even if it's not *quite* as tiny as, say, 3.19-rc2 was (that was really an extreme outlier), 4.10-rc2 is pretty small, and things have generally been fairly quiet. The diffstat is also pretty flat and clean, with the notable exception of the new s390 sha512-based prng. I suspect I should have chomped down on that one too. But the rest really looks like "small fixes", no big new chunks of code.
As usual, it's a mixture of driver fixes, arch updates (with s390 really standing out due to that one prng commit), and some filesystem and networking. The attached shortlog gives the details, there's nothing particularly worrisome here. So far 4.1 looks fairly normal.
