Dave Chinner c0fb4765c5 xfs: convert CIL to unordered per cpu lists 
So that we can remove the cil_lock which is a global serialisation
point. We've already got ordering sorted, so all we need to do is
treat the CIL list like the busy extent list and reconstruct it
before the push starts.

This is what we're trying to avoid:

 -   75.35%     1.83%  [kernel]            [k] xfs_log_commit_cil
    - 46.35% xfs_log_commit_cil
       - 41.54% _raw_spin_lock
          - 67.30% do_raw_spin_lock
               66.96% __pv_queued_spin_lock_slowpath

Which happens on a 32p system when running a 32-way 'rm -rf'
workload. After this patch:

-   20.90%     3.23%  [kernel]               [k] xfs_log_commit_cil
   - 17.67% xfs_log_commit_cil
      - 6.51% xfs_log_ticket_ungrant
           1.40% xfs_log_space_wake
        2.32% memcpy_erms
      - 2.18% xfs_buf_item_committing
         - 2.12% xfs_buf_item_release
            - 1.03% xfs_buf_unlock
                 0.96% up
              0.72% xfs_buf_rele
        1.33% xfs_inode_item_format
        1.19% down_read
        0.91% up_read
        0.76% xfs_buf_item_format
      - 0.68% kmem_alloc_large
         - 0.67% kmem_alloc
              0.64% __kmalloc
        0.50% xfs_buf_item_size

It kinda looks like the workload is running out of log space all
the time. But all the spinlock contention is gone and the
transaction commit rate has gone from 800k/s to 1.3M/s so the amount
of real work being done has gone up a *lot*.
