A Look at What’s Next for the Linux Kernel

Even as more developers are coming to Linux, the pace of development and releases is very fast, Corbet said. He estimates that it now takes approximately 63 days for the community to build a new Linux kernel milestone.

Linux 4.2 will benefit from a number of improvements that have been evolving in Linux over the last several releases. One such improvement is the introduction of OverlayFS, a new type of read-only file system that is useful because it can enable many containers to be layered on top of each other, Corbet said.
