[PATCH] knfsd: remove nfsd_versbits as intermediate storage for desired versions
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.
