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
