The Linux 3.6-rc3 release is coming early since -rc2 took a while and Linus is also spending a few extra days in San Diego prior to next week's events. There's also been pent-up demand for the Linux 3.6-rc3 kernel.
Linus says in his release announcement, "It's a bit over half drivers, with a quarter being arch updates, and the rest being "random" - mostly networking and filesystems. Shortlog appemded, there's nothing here that makes me go "OMG! Scary!" or makes me want to particularly mention it separately. All just random updates and fixes."
