It's not much different from what's there:

I more raised the issue since you pass a 'char *' to setsockopt() but an 'int *'
to getsockopt(), I don't think any other value is non-symmetrical like this.

I meant another cpu can be changing dev->name[] content while the
strcpy() is done, and you get a mangled devname, like "for" or "bao"
instead of "foo" or "bar"

But yes, I obviously understood your point about "char *" and "int *"
