Merge tag 'sched-urgent-2026-03-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull scheduler fixes from Ingo Molnar:
 "More MM-CID fixes, mostly fixing hangs/races:

   - Fix CID hangs due to a race between concurrent forks

   - Fix vfork()/CLONE_VM MMCID bug causing hangs

   - Remove pointless preemption guard

   - Fix CID task list walk performance regression on large systems
     by removing the known-flaky and slow counting logic using
     for_each_process_thread() in mm_cid_*fixup_tasks_to_cpus(), and
     implementing a simple sched_mm_cid::node list instead"
