Subject: Re: [PATCH 01/18] Revert "kvm: selftests: move base kvm_util.h
declarations to kvm_util_base.h"
Sean Christopherson <seanjc@...gle.com> writes:
> Effectively revert the movement of code from kvm_util.h => kvm_util_base.h,
> as the TL;DR of the justification for the move was to avoid #idefs and/or
> circular dependencies between what ended up being ucall_common.h and what
> was (and now again, is), kvm_util.h.
>
> But avoiding #ifdef and circular includes is trivial: don't do that. The
> cost of removing kvm_util_base.h is a few extra includes of ucall_common.h,
> but that cost is practically nothing. On the other hand, having a "base"
> version of a header that is really just the header itself is confusing,
> and makes it weird/hard to choose names for headers that actually are
> "base" headers, e.g. to hold core KVM selftests typedefs.
