    Merge branch 'for-4.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu · a4c20b9a

    Pull percpu updates from Tejun Heo:
     "These are the percpu changes for the v4.13-rc1 merge window. There are
      a couple visibility related changes - tracepoints and allocator stats
      through debugfs, along with __ro_after_init markings and a cosmetic
      rename in percpu_counter.
    
      Please note that the simple O(#elements_in_the_chunk) area allocator
      used by percpu allocator is again showing scalability issues,
      primarily with bpf allocating and freeing large number of counters.
      Dennis is working on the replacement allocator and the percpu
      allocator will be seeing increased churns in the coming cycles"
