Subject[PATCH 22/34] KVM: selftests: Drop unused kvm_userspace_memory_region_find() helper
Date
From: Sean Christopherson <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.
