Linux 7.2 released with cache-aware scheduling and sched_ext sub-schedulers, and the DRM fair scheduler held back to opt-in after a late regression

Sources: Igalia release summary, HN discussion
Summary: Linux 7.2 is the mainline release distributions will pick up. The scheduling work is the substance: cache-aware scheduling, MGLRU improvements, sub-schedulers for sched_ext, and automatic creation of multi-size transparent hugepages. The DRM scheduler fair policy is the exception, because a regression reported during 7.2-rc7 kept the old first-in first-out policy as the default and left fair marked experimental. The cited source is a contributor account rather than the release announcement.
Why it matters: The GPU-sharing improvement is present but off unless a user opts in, so a reader expecting fair DRM scheduling on 7.2 gets the old policy by default.
Follow-up: Track whether the DRM scheduler fair policy becomes the default in a later release and whether the 7.2-rc7 regression is resolved.
