Linux 4.6 Kernel
Here is another big feature coming for the Linux 4.6 kernel.
Following the cgroup pull request for the Linux 4.6 merge window, Tejun Heo sent in a second pull request and it goes ahead to provide cgroup namespaces support for the kernel.
While F2FS still doesn't seem to have been utilized yet by any large, wide-scale deployments as the flash file-system of choice, this Linux file-system continues to mature.
Jaegeuk Kim sent out the pull request this week for updating the Flash-Friendly File-System for Linux 4.6. His pull request needs to be re-submitted to a mistake he made that upset Torvalds, but it gives us a look at the features that are coming for this file-system in the next Linux kernel release.
