Kernel Log: Coming in 2.6.38 (Part 2) – File systems
On Wednesday, Linus Torvalds released the fifth pre-release of kernel version 2.6.38 saying that some regressions have been fixed and other changes are "pretty spread out and small". The Kernel Log therefore takes the opportunity to continue the overview of the major changes in Linux 2.6.38 with the second part of the mini-series "Coming in 2.6.38". Part one discussed the main changes pertaining to graphics drivers, and in the next few weeks we will be discussing network support, storage hardware, drivers, and code for architecture and infrastructure.
Ext family, XFS and Btrfs
In 2.6.38, Ext3 and XFS now support batched discard which was integrated in the 37 kernel and is especially interesting for SSDs with a slow TRIM function (1, 2, 3). In the commit message for the change, Christoph Hellwig explicitly points out that batched discard should not be sent during normal workloads because the search for free space drains performance. In the "XFS status update for January 2011", the kernel hacker mentions some of the XFS changes in 2.6.37 and 2.6.38, including some optimisations to the log subsystem's locking code which considerably improve scalability.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
