Released last month on November 24th, the Linux 5.4 kernel series brings exciting new features for Linux users everywhere, including the long-anticipated support for Microsoft’s proprietary exFAT file system, as well as a new kernel lockdown feature for extra security, and a bunch of improvements for AMD gamers. Linux Kernel 5.4 also adds a new security feature for detecting file tampering called fs-verity, a new dm-clone tool for live cloning of block devices, a new high-performance virtio driver for sharing files between hosts and guests called virtio-fs, improved app memory management on Android devices, and support for Intel Tiger Lake CPUs.
