UKSM Is Still Around For Data Deduplication Of The Linux Kernel

Several years back we wrote about Ultra Kernel Samepage Merging (UKSM) for data de-duplication within the Linux kernel for transparently scanning all application memory and de-duping it where possible. While the original developer is no longer active, a new developer has been maintaining the work and continues to support it on the latest Linux kernel releases.

Phoronix reader Łukasz Żarnowiecki wrote in to share that he's been maintaining UKSM over this time and this week has released the updated version for the Linux 4.10 kernel.

The original project site for those unfamiliar with Ultra Kernel Samepage Merging is at KernelDeDup.org.

The UKSM code that's continuing to be maintained and re-based for the latest Linux kernel repositories is via this GitHub repository for those interested in it.

When he brought up UKSM in an email, I also remembered about PKSM - another Kernel Same Paging approach but that project site hasn't indicated any activity now since 2013.
