[PATCH v12 02/45] KVM: guest_memfd: Use kvm_mem_is_private() when populating guest_memfd memory

[Ackerley Tng via B4 Relay]

From: Sean Christopherson <seanjc@xxxxxxxxxx>

Use kvm_mem_is_private() when populating guest_memfd instead of using an
open coded equivalent.  In addition to simplifying the populate code *now*,
this avoids the need to provide a range-based gmem lookup API in the future
as well.

No functional change intended.
