Process File Descriptors on Linux

Explore the concept of process file descriptors (pidfds) on Linux in this 47-minute conference talk from the Linux Plumbers Conference. Dive into the challenges of traditional process identification using PIDs and learn how pidfds solve issues related to PID recycling and maintaining stable process references. Examine the implementation details, upstream contributions, and future plans for pidfds. Gain insights into how this innovation improves process management for system managers and userspace OOM killers. Follow along as Christian Brauner discusses the various approaches considered and the solutions implemented to enhance process handling in Linux systems.
