CONFIG_JUMP_LABEL says the user wants to use jump labels. But we also need the toolchain to support it. That is reflected in CC_HAVE_ASM_GOTO=y, and if both are set then HAVE_JUMP_LABEL is set to true. > I don't understand this patch. > > What is the problem you are fixing? There is basically no real problem here. This patch only tries to make kernel code that using static_key infrastructure appears "unified" > > The intent is to only use static_key infrastructure > if user has enabled CONFIG_JUMP_LABEL. The other parts of kernel either use #ifdef HAVE_JUMP_LABEL, or use no "#ifdef" at all(the two exceptions are netfilter and powerpc modules which I send patches to both). Jason has suggested me to make the patches: https://lkml.org/lkml/2014/8/20/761 "Unified" is the reason, I guess :-) so rookies like me can have unified examples to follow Cheers Zhouyi -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
