Sean Christopherson <seanjc@google.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. > > For all intents and purposes, this reverts commit > 7d9a662ed9f0403e7b94940dceb81552b8edb931. > > Signed-off-by: Sean Christopherson <seanjc@google.com> > --- > .../selftests/kvm/aarch64/arch_timer.c | 1 + > tools/testing/selftests/kvm/arch_timer.c | 1 + > .../selftests/kvm/demand_paging_test.c | 1 + > .../selftests/kvm/dirty_log_perf_test.c | 1 + > tools/testing/selftests/kvm/dirty_log_test.c | 1 + > .../testing/selftests/kvm/guest_memfd_test.c | 2 +- > .../testing/selftests/kvm/guest_print_test.c | 1 + > .../selftests/kvm/include/aarch64/processor.h | 2 + > .../selftests/kvm/include/aarch64/ucall.h | 2 +- > .../testing/selftests/kvm/include/kvm_util.h | 1128 +++++++++++++++- > .../selftests/kvm/include/kvm_util_base.h | 1135 ----------------- > .../selftests/kvm/include/s390x/ucall.h | 2 +- > .../selftests/kvm/include/x86_64/processor.h | 3 +- > .../selftests/kvm/include/x86_64/ucall.h | 2 +- > .../selftests/kvm/kvm_page_table_test.c | 1 + > .../selftests/kvm/lib/aarch64/processor.c | 2 + > tools/testing/selftests/kvm/lib/kvm_util.c | 1 + > tools/testing/selftests/kvm/lib/memstress.c | 1 + > .../selftests/kvm/lib/riscv/processor.c | 1 + > .../testing/selftests/kvm/lib/ucall_common.c | 5 +- > .../testing/selftests/kvm/riscv/arch_timer.c | 1 + > tools/testing/selftests/kvm/rseq_test.c | 1 + > tools/testing/selftests/kvm/s390x/cmma_test.c | 1 + > tools/testing/selftests/kvm/s390x/memop.c | 1 + > tools/testing/selftests/kvm/s390x/tprot.c | 1 + > tools/testing/selftests/kvm/steal_time.c | 1 + > .../x86_64/dirty_log_page_splitting_test.c | 1 + > .../x86_64/exit_on_emulation_failure_test.c | 2 +- > .../kvm/x86_64/ucna_injection_test.c | 1 -

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. For all intents and purposes, this reverts commit 7d9a662ed9f0403e7b94940dceb81552b8edb931.
