Oh, I did wrong assumption. However, it looks like linux-stable 3.0.y
is affected;

  CC [M]  samples/kfifo/inttype-example.o
samples/kfifo/inttype-example.c:44:506: warning: missing initializer
[-Wmissing-field-initializers]
samples/kfifo/inttype-example.c:44:506: warning: (near initialization
for ‘(anonymous).buf’) [-Wmissing-field-initializers]

And it seems that my solution not the one which is used in linux-next.

gcc (Debian 4.7.2-2) 4.7.2
