Description B. Keroack 2004-06-20 14:24:20 UTC

As of 2.6.7, gentoo-dev-sources no longer contains the Con Kolivas autoregulated swappiness patch. This is important for desktop machines, to avoid having large amounts of memory swapped out on prolonged system inactivity (causing an annoying swapstorm when the machine is used again). 

The patch may decrease throughput slightly but increases interactivity/latency. The patchset referenced in bug #51800 contains a compile-time config option for autoregulated swappiness which I think is a good compromise.

It is not "important" :)

Anyway, no, I will not include these patches in the main gentoo-dev-sources tree.

If you want to use Con's patches, please use his kernel tree (I think it's available in the sys-kernel/ck-sources package.)
