If TEST_F() explicitly calls exit(code) with code different than 0, then _metadata->exit_code is set to this code (e.g. KVM_ONE_VCPU_TEST()). We need to keep in mind that _metadata->exit_code can be KSFT_SKIP while the process exit code is 0.
Initial patch written by Sean Christopherson [1].
Heh, my pseudo patch barely has any relevance at this point. How about replacing that with:

Changes since v4:
- Check abort status when the grandchild exited.
- Keep the _exit(0) calls because _metadata->exit_code is always checked.
- Only set _metadata->exit_code to WEXITSTATUS() if it is not zero.
Changes since v3:
- New patch mainly from Sean Christopherson.

Ah, IIUC, this works because __run_test() effectively forwards the exit_code?
} else if (t->pid == 0) { setpgrp(); t->fn(t, variant); _exit(t->exit_code); }
