The third development installment to the Linux 3.9 kernel is now available. There were more changes than found in Linux 3.9-rc2, but overall it appears in good shape.
Linus Torvalds' brief 3.9-rc3 release announcement reads, "Not as small as -rc2, but that one really was unusually calm. So there was clearly some pending stuff that came in for -rc3, with network drivers and USB leading the charge. But there's other misc drivers, arch updates, btrfs fixes, etc etc too."
