From: Ackerley Tng <[email protected]> Move kvm_supported_mem_attributes() from kvm_main.c to kvm_host.h and make it a static inline function. This allows the helper to be used in other parts of the KVM subsystem outside of kvm_main.c. This helper will be used later by guest_memfd.
No functional change intended.
