      Merge branch 'slab/for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/linux · 54be8200
      Linus Torvalds authored
      Pull slab update from Pekka Enberg:
       "Highlights:
      
        - Fix for boot-time problems on some architectures due to
          init_lock_keys() not respecting kmalloc_caches boundaries
          (Christoph Lameter)
      
        - CONFIG_SLUB_CPU_PARTIAL requested by RT folks (Joonsoo Kim)
      
        - Fix for excessive slab freelist draining (Wanpeng Li)
      
        - SLUB and SLOB cleanups and fixes (various people)"
      
      I ended up editing the branch, and this avoids two commits at the end
      that were immediately reverted, and I instead just applied the oneliner
      fix in between myself.

      Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
      with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
      disable migration. But the SLUB code is relatively lockless, and the
      spin_locks there are raw_spin_locks (not converted to mutexes), thus I
      believe this bug can happen in mainline without -rt features. The -rt
      patch is just good at triggering mainline bugs ;-)
      
      Anyway, looking at where this crashed, it seems that the page variable
      can be NULL when passed to the node_match() function (which does not
      check if it is NULL). When this happens we get the above panic.
      
      As page is only used in slab_alloc() to check if the node matches, if
      it's NULL I'm assuming that we can say it doesn't and call the
      __slab_alloc() code. Is this a correct assumption?
