Sakari, JFYI. I remember during some reviews we have a discussion
about {0} vs {} and surprisingly they are not an equivalent.

Of course, this is the difference between "{ 0 }" and "{}"

initializations.

Really?  Neither will handle structures with holes in it, try it and
see.

{} is a GCC extension, but I never thought it works differently.

Yes, this is GCC extension and kernel relies on them very heavily.

I guess simple people who contribute to the kernel just haven't
realized (yet) that it's an extension and that's why we have plenty of
{} and {0} in the kernel.

And if true, where in the C spec does it say that?
