The 2019 version of the Linux Storage, Filesystem, and Memory-Management Summit opened with a plenary talk by Brendan Gregg on observing the state of Linux systems using BPF. It is, he said, an exciting time; the BPF-based "superpowers" being added to the kernel are growing in capability and maturity. It is now possible to ask many questions about what is happening in a production Linux system without the need for kernel modifications or even basic debugging information.
