Linux Torvalds mentions that “Feature-wise, 4.0 do not 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 also been made to Memory management, Virtualization, Security and Networking modules.
Linus Torvalds says that the Linux 4.1 is likely to be a ‘bigger release’. So we can expect more from the next release.
