Subject: [PATCH] ipv4/fib: don't warn when primary address is missing if
|
|
in_dev is dead
|
|
|
|
After commit fbd40ea0180a ("ipv4: Don't do expensive useless work
|
|
during inetdev destroy.") when deleting an interface,
|
|
fib_del_ifaddr() can be executed without any primary address
|
|
present on the dead interface.
|
|
|
|
The above is safe, but triggers some "bug: prim == NULL" warnings.
|
|
|
|
This commit avoids warning if the in_dev is dead
