Linux 4.0

The article I read is: Linux 4.0 brings Skynet closer to existence, offers reboot-free kernel patching.

While it probably won't be mainstream all that soon, I do look forward to reboot-free kernel upgrades, since it will make things a bit more convenient than it already is (considering that a Linux user can reboot/relog at their own convenience without a nag message).

The other thing that will be nice about 4.0 is the audio over HDMI with the open-source AMD Radeon driver; this will be quite nice for a media PC or HTPC, since it doesn't require the workaround. To make it work with 3.x, you would have to tweak a setting or two, but it can cause issues (I tried it once for the heck of it, but it was a long while ago, so I don't remember all that much of what happened).

As for the numerical numbering, it doesn't matter to me if it's 4.0 or 3.2 because it's just a numerical sequence after all.
