The multi-queue block layer (blk-mq) has indeed made it for Linux 3.13 as one (of many other) exciting features. The multi-queue block layer can lead to better SSD performance through reducing latency by balancing I/O workload across multiple CPU cores and allowing for multiple hardware queues.

The merge window hasn't even officially opened yet on the Linux 3.13 kernel but it's already super exciting and I can't wait for the new code to start hitting mainline and to benchmark these massive changes to the Linux kernel. Here's just a few things to expect so far but it's already gearing up to be a super exciting release and perhaps the best of 2013.

The Linux 3.13 kernel merge window has become even more exciting even though it's not even officially open yet. Besides many to-be-merged changes talked about on Phoronix already, the ACPI and power management pull is particularly exciting for ARM and Intel Linux users.

While the Linux 3.13 merge window isn't opening until next week, the maintainer of the block layer to the Linux kernel isn't accepting anymore changes for this next kernel release. The merge pull for the block layer in Linux 3.13 is already quite large, in part due to merging the multi-queue block layer (blk-mq) support for faster disk performance. The multi-queue block layer will allow Linux to perform significantly better for disk IOPS while reducing latency with multi-queue SSD access on multi-core systems.

As was anticipated, the Linux 3.12 kernel was released this afternoon. The Linux 3.12 kernel is a mighty big update but beyond announcing its debut, Linus Torvalds also made mention of a delay in the Linux 3.13 merge window and has begun expressing possible plans for a Linux 4.0 release in about one year's time.

While the Linux 3.12 kernel hasn't even been released yet, going back to late August Intel has been plotting their graphics improvements for Linux 3.13. In September Intel was already sending in drm-next changes and they have done more rounds since. Another drm-next pull request was issued today for the Intel DRM driver.
