New Linux Patches Aim To Customize Out-Of-Memory Behavior Using BPF

New Linux patches introduce the ability to customize the out-of-memory (OOM) behavior using BPF programs. The patches focus on allowing flexible OOM handling policies and PSI-based OOM invocation. Unlike previous proposals, this approach aims to be more generic, enabling more precise control over memory management, such as task selection or memory cgroup handling. This eliminates the need for additional userspace daemons and infrastructure, offering a more integrated solution within the kernel.
