2002-04-11 Zack Weinberg <zack@codesourcery.com> * include/rpc/rpc.h (struct rpc_thread_variables): Remove authnone_private_s. * sunrpc/auth_none.c: Include bits/libc-lock.h. Delete #ifdef _RPC_THREAD_SAFE_ block. (authnone_private): Make a struct, not a pointer to struct. (authnone_private_guard): New once-control variable. (authnone_create_once): New function, split out of authnone_create. No need to allocate memory. (authnone_create): Just call authnone_create_once via __libc_once, then return &authnone_private->no_client. (authnone_marshal): Access private data via CLIENT argument, not authnone_private pointer. Fix typo (MAX_MARSHEL_SIZE -> MAX_MARSHAL_SIZE). * sunrpc/rpc_thread.c (__rpc_thread_destroy): No need to free authnone_private_s.
