-Subject: [PATCH 327/347] mm: slub: Always flush the delayed empty slubs in
- flush_all()
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz

-[ Upstream commit 23a2c31b19e99beaf5107071b0f32a596202cdae ]
-
-After commit f0b231101c94 ("mm/SLUB: delay giving back empty slubs to
-IRQ enabled regions"), when the free_slab() is invoked with the IRQ
-disabled, the empty slubs are moved to a per-CPU list and will be
-freed after IRQ enabled later. But in the current codes, there is
-a check to see if there really has the cpu slub on a specific cpu
-before flushing the delayed empty slubs, this may cause a reference
-of already released kmem_cache in a scenario like below:
-	cpu 0				cpu 1
-  kmem_cache_destroy()
-    flush_all()
-                         --->IPI       flush_cpu_slab()
-                                         flush_slab()
-                                           deactivate_slab()
-                                             discard_slab()
-                                               free_slab()
-                                             c->page = NULL;
-      for_each_online_cpu(cpu)
-        if (!has_cpu_slab(1, s))
-          continue
-        this skip to flush the delayed
-        empty slub released by cpu1
-    kmem_cache_free(kmem_cache, s)
-
-                                       kmalloc()
-                                         __slab_alloc()
-                                            free_delayed()
-                                            __free_slab()
-                                            reference to released kmem_cache
