Subject: [PATCH 06/10] KVM: nVMX: Convert local exit_reason to u16 in ...enter_non_root_mode()
Date: Thu, 12 Mar 2020 11:45:17 -0700	[thread overview]
Message-ID: <20200312184521.24579-7-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200312184521.24579-1-sean.j.christopherson@intel.com>

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.
