Hmm, I generally agree, but in this case I think there's value in having the names *not* stand out, because they really are uninteresting and would ideally blend in. I can't envision a scenario where we don't want to assert on an OOM, i.e. there should never be a need to use a raw malloc(), and so I don't see much value in making it obvious that the call sites are doing something special. > > > I'm not a huge fan of capital letters, but we could also do something like > > > MALLOC()/CALLOC(). > > > > Hmm, I'm not usually a fan either, but that could actually work quite well in this > > case.

How about TEST_MALLOC() / > TEST_CALLOC(). It is vaguely similar to TEST_ASSERT(), which I'd hope > would give the impression that an assertion is lurking below. Yeah, but it could also give the false impression that the macro does something fancier, e.g. this makes me want to peek at TEST_MALLOC() to see what it's doing cpuid = TEST_MALLOC(kvm_cpuid2_size(nr_entries)); whereas this isn't quite enough to pique my curiosity. cpuid = MALLOC(kvm_cpuid2_size(nr_entries)); So I have a slight preference for just MALLOC()/CALLOC(), but I'm also ok with a TEST_ prefix, my brain can adapt. One of those two flavors has my vote.
