[PATCH v3 14/15] KVM: Use kvm_userspace_memory_region_ext |
|
Date: |
Tue, 21 Dec 2021 23:11:24 +0800 |
Use the new extended memslot structure kvm_userspace_memory_region_ext
which includes two additional fd/ofs fields comparing to the current
kvm_userspace_memory_region. The fields fd/ofs will be copied from
userspace only when KVM_MEM_PRIVATE is set.
Internal the KVM we change all existing kvm_userspace_memory_region to
kvm_userspace_memory_region_ext since the new extended structure covers
all the existing fields in kvm_userspace_memory_region.
