    [PATCH] knfsd: remove nfsd_versbits as intermediate storage for desired versions · 6658d3a7
    NeilBrown authored
    We have an array 'nfsd_version' which lists the available versions of nfsd,
    and 'nfsd_versions' (poor choice there :-() which lists the currently active
    versions.
    
    Then we have a bitmap - nfsd_versbits which says which versions are wanted.
    The bits in this bitset cause content to be copied from nfsd_version to
    nfsd_versions when nfsd starts.
    
    This patch removes nfsd_versbits and moves information directly from
    nfsd_version to nfsd_versions when requests for version changes arrive.
    
    Note that this doesn't make it possible to change versions while the server is
    running.  This is because serv->sv_xdrsize is calculated when a service is
    created, and used when threads are created, and xdrsize depends on the active
    versions.
