History
Matthew Dillon 479112dfd9 Remove inappropriate VOP_FSYNC from vm_object_page_clean(). The fsync 
syncs the entire underlying file rather then just the requested range,
    resulting in huge inefficiencies when the VM system is articulated in
    a certain way.  The VOP_FSYNC was also found to massively reduce NFS
    performance in certain cases.

    Change MADV_DONTNEED and MADV_FREE to call vm_page_dontneed() instead
    of vm_page_deactivate().  Using vm_page_deactivate() causes all
    inactive and cache pages to be recycled before the dontneed/free page
    is recycled, effectively flushing our entire VM inactive & cache
    queues continuously even if only a few pages are being actively MADV
    free'd and reused (such as occurs with a sequential scan of a
    memory-mapped file).
