Merge tag 'sched_ext-for-6.18-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext fixes from Tejun Heo:

 - Fix scx_kick_pseqs corruption when multiple schedulers are loaded
   concurrently

 - Allocate scx_kick_cpus_pnt_seqs lazily using kvzalloc() to handle
   systems with large CPU counts

 - Defer queue_balance_callback() until after ops.dispatch to fix
   callback ordering issues

 - Sync error_irq_work before freeing scx_sched to prevent
   use-after-free

 - Mark scx_bpf_dsq_move_set_[slice|vtime]() with KF_RCU for proper RCU
   protection

 - Fix flag check for deferred callbacks
