Linus Torvalds fd57572253 sched_ext: Fixes for v6.18-rc3
- 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
