      Two fixes for SLAB and SLUB
      
      - Make it possible to use kmem_cache_alloc_bulk() early in boot when
        interrupts are not yet enabled, as code doing that start to appear via
        the maple tree (by Thomas Gleixner).
      - Fix debugfs-related memory leak (by Greg Kroah-Hartman).

      mm, slab/slub: Ensure kmem_cache_alloc_bulk() is available early · f5451547
      Thomas Gleixner authored
      The memory allocators are available during early boot even in the phase
      where interrupts are disabled and scheduling is not yet possible.
      
      The setup is so that GFP_KERNEL allocations work in this phase without
      causing might_alloc() splats to be emitted because the system state is
      SYSTEM_BOOTING at that point which prevents the warnings to trigger.
      
      Most allocation/free functions use local_irq_save()/restore() or a lock
      variant of that. But kmem_cache_alloc_bulk() and kmem_cache_free_bulk() use
      local_[lock]_irq_disable()/enable(), which leads to a lockdep warning when
      interrupts are enabled during the early boot phase.
      
      This went unnoticed so far as there are no early users of these
      interfaces. The upcoming conversion of the interrupt descriptor store from
      radix_tree to maple_tree triggered this warning as maple_tree uses the bulk
      interface.
      
      Cure this by moving the kmem_cache_alloc/free() bulk variants of SLUB and
      SLAB to local[_lock]_irq_save()/restore().
      
      There is obviously no reclaim possible and required at this point so there
      is no need to expand this coverage further.
      
      No functional change.
