Released on August 2nd, 2020, the Linux 5.8 kernel series was dubbed as ???one of the biggest releases of all time by Linus Torvalds. It brought numerous new features and enhancements, such as support for LZO-RLE compression in the F2FS file system, inline encryption support for the block layer, a new faccessat2() system call, a new initrdmem= boot option for specifying an initial RAM disk image, and a new CAP_PERFMON functionality. But, as all good things most come to an end, and since Linux kernel 5.8 was not a long-term supported branch, it will no longer receive further updates that address important bugs and security issues. Linux kernel 5.8.18 is the last update in the series, and if you’re using it you should consider upgrading to the latest Linux kernel 5.9 series as soon as possible after reading this.
