A second version of the Zswap patch-set for the Linux kernel was published this week. The Zswap patches provide compressed swap caching support to compress pages in the process of being swapped and compresses them into a dynamically allocated RAM-backed memory pool.

KTAP is an experimental project that's a new dynamic tracing tool for Linux. KTAP has several different design principles from SystemTap, one of the current most common dynamic instrumentation and tracing tools for Linux. This new project might satisfy some of those developers that have been wanting Sun/Oracle's DTrace to come to Linux.

A few months ago I wrote about hot-data tracking for the Linux kernel, a VFS feature that could be used by Btrfs and other Linux file-systems for delivering improved performance. Unfortunately the patch-set didn't make the new Linux 3.8 development cycle, but hot-data tracking is still being worked on for merging into a future Linux kernel release.

Dynticks, the Dynamic Tick Timer for allowing the Linux kernel to skip ticks while idling and resume to running at full HZ when encountering load, is in the process of being extended. Developers are working on making Dynticks work even under select workloads in order to enhance the performance of CPU-intensive tasks.
