In order to fix this, I need to change -I../../../../usr/include/ for
$(KHDR_INCLUDES) in tools/testing/selftests/rseq/Makefile
I can find 25 odd uses of the same pattern in the kernel selftests.
Should I fix them all in one go ?
grep -r "../../../../usr/include/" tools/testing/selftests/ | wc -l
25
AFAIU it typically works just because the build system happens to have
recent enough kernel headers installed in the root environment.
Thanks,
Mathieu
