commit 9ee41317adde8e0d9da889745673cb909f40eb2b
Author: Peter Xu <peterx@redhat.com>

    memory: Rename memory_region_has_guest_memfd() to *_private()

    Rename the function with "_private" suffix, to show that it returns true
    only if it has an internal guest-memfd to back private pages (rather than
    fully shared guest-memfd).
