"Bug" in nfs_server_get_key() ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Sorry if this is a 'known' issue, but I've been looking at nfs_server_get_key() in fs/nfs/fscache-index.c and I'm not sure why the code is doing:

        key->nfsversion = clp->rpc_ops->version;
        key->family = clp->cl_addr.ss_family;

        memset(key, 0, len);

Unless I'm missing something, it sets nfsversion and family in key to appropriate values - but then immediately sets both these to zero via the memset() ?

I guess it can't be 'fixed' as it would result if different keys being generated for the same file system pre and post fix ?

Thanks
