AI-suggested
A fix is available that prevents the warning by checking for boosted tasks before calling setup_new_dl_entity. Users should update to the patched Linux kernel version that includes this fix. No additional mitigation is required beyond applying the official patch.
Description
A warning issue in the Linux kernel's sched/deadline subsystem related to boosted tasks has been fixed. The warning occurs when set_cpus_allowed dequeues and enqueues tasks with the ENQUEUE_RESTORE flag, triggering a WARN_ON call for boosted tasks unnecessarily. The fix avoids calling setup_new_dl_entity for boosted tasks during requeueing.
