      Fix kmem_cache_free performance regression in slab · 80cbd911
      Matthew Wilcox authored
      The database performance group have found that half the cycles spent
      in kmem_cache_free are spent in this one call to BUG_ON.  Moving it
      into the CONFIG_SLAB_DEBUG-only function cache_free_debugcheck() is a
      performance win of almost 0.5% on their particular benchmark.
      
      The call was added as part of commit ddc2e812
      with the comment that "overhead should be minimal".  It may have been
      minimal at the time, but it isn't now.
      
      [ Quoth Pekka Enberg: "I don't think the BUG_ON per se caused the
        performance regression but rather the virt_to_head_page() changes to
        virt_to_cache() that were added later." ]
