    [PATCH] A basic NFSv4 client for 2.5.x · 63a5ba42

    This is a nontrivial change to the NFS client.
    
    In this patch, we finish modifying the async READ path so that it is
    version-agnostic.  We define a new nfs_rpc_op ->setup_read(), and move
    the v2- and v3-specific code in nfs_read_rpcsetup() there.  We also
    have to change nfs_readpage() result so that the 'count' of bytes
    read is a parameter.  The extra parameter means that it can no longer
    be ->tk_exit().  Instead, it is called from a version-specific ->tk_exit()
    routine which is set in ->read_setup().
    
    The upshot of all this is that the version-specific part of the
    async READ path has been encapsulated in a new nfs_rpc_op
    ->read_setup(), and NFSv4 can share the logic for asynchronous
    READ's with NFSv2 and v3.
