  SVN rev 205231 on 2010-03-16 22:17:21Z by kmacy
  
  - reduce contention by breaking up ARC state locks in to 16 for data
    and 16 for metadata
  - export L2ARC tunables as sysctls
  - add several kstats to track L2ARC state more precisely
  - avoid holding a contended lock when atomically incrementing a
    contended counter (no lock protection needed for atomics)
