Soft scrollback for the Linux VGA console

If you're a heavy user of the Linux VGA console, you'll like this feature. Recent 2.6 kernels have added support for soft scrollback. This feature enables you to have much bigger scrollback buffer than the standard console has, at the price of slightly slower console output.

The scrollback buffer of the standard VGA console is located in VGA RAM. This RAM is fixed in size and is very small. To make the scrollback buffer larger, it must be placed instead in System RAM. We call this soft scrollback.

CFQ to become the default I/O scheduler in 2.6.18

Judging by this commit, CFQ (Complete Fair Queuing) I/O scheduler will become the default one in the upcoming 2.6.18 kernel. For a long time, anticipatory scheduler has been the default, although even back in late 2004 there was some thinking about replacing it with CFQ. And it seems the time has finally come.
