  log: |
    sys: Use membar_release/acquire around reference drop.

    This just goes through my recent reference count membar audit and
    changes membar_exit to membar_release and membar_enter to
    membar_acquire -- this should make everything cheaper on most CPUs
    without hurting correctness, because membar_acquire is generally
    cheaper than membar_enter.
