Subject[PATCH 06/10] KVM: nVMX: Convert local exit_reason to u16 in ...enter_non_root_mode()
Date
Use a u16 for nested_vmx_enter_non_root_mode()'s local "exit_reason" to
make it clear the intermediate code is only responsible for setting the
basic exit reason, e.g. FAILED_VMENTRY is unconditionally OR'd in when
emulating a failed VM-Entry.

No functional change intended.
