I think we don't need to initialize this, right?
We actually do have to initialized it because in the unlikely case that the
code block inside the 'if' below is not executed, then we will end up
freeing an uninitialized pointer.
I see, you're right indeed.
We can probably simplify this code, but just doing:
I wonder if it is better to code this instead:
netlink attribute parsing here.
You could even remove the likely() thing, which doesn't make much
sense for control plane code.
Why is that?
I understand this is a larger change, but I think this function will
look better while we're removing VLA.
Would you mind having a look? I'd appreciate if so.
I can do that. No problem.
