System calls grow old and show their age too. That is exactly the case of futex(), a fast synchronization mechanism for userspace added in the good old days 2.X kernels, hence kernel developers have been trying to improve its performance and add new features to cope with the requirements of more modern workloads. However, during these discussions in the mailing list one thing became very clear: we need a new version of the syscall, that can enable not only more complex use cases but also key performance improvement inside the kernel. This talk will present the challenges the new interface should address, the current progress on this new interface development, besides the outcomes from Linux Plumbers Conferece 2020.
