FYI in the past I was thinking about further automation of test variant,
thus I added variant_desc (see accept4_01.c). But nowadays most of the test
variants are using struct test_variants (mostly due time64 support thus they use
time64_variants.h). It looks to me only accept4_01.c and epoll_create0[12].c you
just ported, so any optimisation for non-time64 tests is not relevant any more.

Kind regards,
Petr
