It's Sunday afternoon, which means it's time for the usual release candidate.
Things are fairly normal, although rc6 is a bit bigger than I would have liked to see. There's no single reason for that, it's just various changes all over.
Networking (both drivers and core) is perhaps the most noticeable part, at roughly a quarter of the changes, but there's a little bit of everything in there outside of that: other drivers (gpu, dma, iio, sound, usb, misc..), the usual architecture updates (arm, mips, x86, powerpc), along with a few filesystem and core kernel updates. And another batch of selftest updates.
So while I would have wished for less at this point, nothing in there looks all that odd or scary. I think we're still solidly on track for a normal release.
