[PATCH] RPC: [PATCH] improve rpcauthauth_create error returns
Currently we return -ENOMEM for every single failure to create a new auth.
This is actually accurate for auth_null and auth_unix, but for auth_gss it's a
bit confusing.
Allow rpcauth_create (and the ->create methods) to return errors. With this
patch, the user may sometimes see an EINVAL instead. Whee.
