Linux Torvalds mentions that “Feature-wise, 4.0 doesn’t have all that much special. Much have been made of the new kernel patching infrastructure, but realistically we’ve had much bigger changes in other versions. So this is very much a ‘solid code progress’ release.
However let’s see what’s new about the 4.0 Kernel release
- You can now install new kernel update without rebooting your system. Though a minor update for desktop users, it’s a major relief for server users.
- DAX – Direct Access, for persistent memory storage
- Support Parallel NFS server, default to NFS v4.2
- The new release supports Intel Quark SoC support
- Patches has been released to improve Linux on Playstation 3
- File System tweaks, including F2FS, BtrfFS, etc.
- Notable to minor changes has been also made to Memory management, Virtualization, Security and Networking moduels.
Linus Torvalds says that the Linux 4.1 is likely to be a ‘bigger release’. So we can expect more from the next release.
