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?
It seems you've merged v2. I will post additional patches to use tools/lib/librseq.so, depending on what Mathieu will have.
Mathieu, Please let me know if there are anything I can help.
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 index 690b499c3471..6c192b0ec304 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -37,6 +37,7 @@ ifeq ($(ARCH),riscv) UNAME_M := riscv endif

and just #include "../rseq/rseq.c" in rseq_test.c.
Thanks, Gavin
