Another way to ask this, is why are these symbols no longer exported (previously exported in core.c with EXPORT_SYMBOL_GPL), and how are people who built lkm's using the previously existing interface supposed to port them? Is it perhaps documented somewhere? I have not been able to find this via google or in git comments.
Is this the wrong forum for this question (which I grant may be a "newbie" question), or is there just no good answer? thanks, chris > I am trying to get my linux kernel module that extends perf support to work > in a later kernel version.
