Indeed, this hack seems to be a good approach to immediately fix things without
moving around all source files and headers. In the longer term, I'd prefer Sean's
proposal to move rseq.c to tools/lib/ (and to move rseq headers to tools/include/rseq/).
This can be done in a follow up phase though. I'll put a note on my todo list
for after I come back from vacation.
Great, Gavin, are you going to repost using librseq?
Yeah, rseq_test should reuse librseq code. The simplest way,
if slightly hackish, is to do something like
diff --git a/tools/testing/selftests/kvm/Makefile
b/tools/testing/selftests/kvm/Makefile

and just #include "../rseq/rseq.c" in rseq_test.c.
