Released by Linus Torvalds last week, Linux kernel 5.8 is dubbed as one of the biggest kernel releases of all time and brings with it numerous new features, updated hardware support, and several security enhancements. Highlights of the Linux 5.8 kernel series include Shadow Call Stack and Branch Target Identification (BTI) support for ARM architectures, LZO-RLE compression support in the F2FS file system, a new boot option for specifying an initial RAM disk image, and a new event-notification mechanism.
