Anatomy of Linux Kernel Shared Memory

Posted by kdawson on from the culture-by-another-name dept.

An anonymous reader sends in an IBM DeveloperWorks backgrounder on Kernel Shared Memory in the 2.6.32 Linux kernel. KSM allows the hypervisor to increase the number of concurrent virtual machines by consolidating identical memory pages. The article covers the ideas behind KSM (such as storage de-duplication), its implementation, and how you manage it.

    Spoken like someone who has never used a piece of open source software in their life.

    Open Source Software: one group of people write the software, a second team compile it, a third bunch of people "test" it, and sometimes the fourth group, of people who actually use it, is non-empty.

    As far as I can tell, the four groups are mutually exclusive. It's pretty obvious non of the developers actually use this crap.

    Who cares about the documentation? It will just end up out of date, people seem to enjoy throwing away all the old code and re-writing some half-assed replacement.
