Subject: [PATCH v13 24/35] KVM: selftests: Drop unused kvm_userspace_memory_region_find() helper
Date: Fri, 27 Oct 2023 11:22:06 -0700 [thread overview]
Message-ID: <20231027182217.3615211-25-seanjc@google.com> (raw)
In-Reply-To: <20231027182217.3615211-1-seanjc@google.com>
Drop kvm_userspace_memory_region_find(), it's unused and a terrible API
(probably why it's unused). If anything outside of kvm_util.c needs to
get at the memslot, userspace_mem_region_find() can be exposed to give
others full access to all memory region/slot information.
