    Phoronix: OPTPOLINES - Formerly Relpolines, Lower Overhead To Retpolines For Spectre Mitigation

    It's been nearly one year to the day since the Spectre and Meltdown vulnerabilities were made public. While the security vulnerabilities were quickly buttoned up in the Linux space, kernel developers continue working to offset the performance overhead introduced by these mitigations. They made a lot of overhead reductions in 2018 while still there are some patch-sets pending still for bettering the experience. One of these patch-sets was known as "Relpolines" but now has been updated and morphed into what is being called Optpolines...
