[PATCH net 2/3] ipvs: add a 'default' case in do_ip_vs_set_ctl()

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

 



From: Li Qiong <liqiong@xxxxxxxxxxxx>

It is better to return the default switch case with
'-EINVAL', in case new commands are added. otherwise,
return a uninitialized value of ret.
