Samsung Keeps Tuning F2FS File-System Performance

It's been almost one and a half years since Samsung introduced the F2FS file-system. Samsung's game-plan for F2FS still isn't yet clear with not having seen any widespread flash deployments yet on consumer devices, but regardless, it's continuing to receive new improvements and features each Linux kernel update.

The 50 Watt Power Regression Is Believed To Be Fixed

Near the beginning of the month I wrote about an Intel developer finding a Linux kernel power regression increasing the system's power use by 50 Watts. After extensive testing and investigating, the issue has been fixed ahead of the Linux 3.13 kernel release and is proposed for stable point releases on the 3.10, 3.11, and 3.12 kernels.
