4 | Subject: [PATCH] network: remove redunant link name in message |
5 | |
6 | Fixes #12454. |
7 | |
8 | gcc was complaining that the link->ifname argument is NULL. Adding |
9 | assert(link->ifname) right before the call has no effect. It seems that |
10 | gcc is confused by the fact that log_link_warning_errno() internally |
11 | calls log_object(), with link->ifname passed as the object. log_object() |
12 | is also a macro and is does a check whether the passed object is NULL. |
13 | So we have a check if something is NULL right next an unconditional use |
14 | of it where it cannot be NULL. I think it's a bug in gcc. |
15 | |
16 | Anyway, we don't need to use link->ifname here. log_object() already prepends |
17 | the object name to the message. |
