Merge tag 'slab-fixes-for-6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab 

Pull slab fix from Vlastimil Babka:

  that can cause a crash. It hasn't been found earlier due to quite
  specific conditions necessary (OOM during kmem_cache_alloc_bulk())"

* tag 'slab-fixes-for-6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
