[PATCH v5 09/12] machine: Rename machine_require_guest_memfd() to *_private()

[Michael Roth <michael.roth@amd.com>]

From: Peter Xu <peterx@redhat.com>

Differenciate it from fully shared guest-memfd use cases.

When at it, add proper brackets in kvm_handle_hc_map_gpa_range() otherwise
checkpatch may complain.
