    nfs: add mirroring support to pgio layer · a7d42ddb
    Weston Andros Adamson authored
    This patch adds mirrored write support to the pgio layer. The default
    is to use one mirror, but pgio callers may define callbacks to change
    this to any value up to the (arbitrarily selected) limit of 16.
    
    The basic idea is to break out members of nfs_pageio_descriptor that cannot
    be shared between mirrored DSes and put them in a new structure.
