I saw this function invocation, trace_kfree_skb(skb, __builtin_return_address(0));
so I grepped the source for "trace_kfree_skb", but I found no where it's defined.
For some uses, the Linux kernel forms a definition via the preprocessor, by gluing together several strings. Try doing 'git grep trace_##' (or 'grep -r trace_## .' if you don't have a git tree.
