From: Wang Nan <[email protected]> Commit 0b3c2264ae30 ("perf symbols: Fix kallsyms perf test on ppc64le") refers struct symbol in probe_event.h, but forgets to include its definition. Gcc will complain about it when that definition is not added, by sheer luck, by some other header included before probe_event.h.
