Subject: [PATCH v14 01/11] KVM: x86/vmx: Make vmx_set_intercept_for_msr() non-static
Date: Mon,  1 Feb 2021 13:10:29 +0800	[thread overview]
Message-ID: <20210201051039.255478-2-like.xu@linux.intel.com> (raw)
In-Reply-To: <20210201051039.255478-1-like.xu@linux.intel.com>

To make code responsibilities clear, we may resue and invoke the
vmx_set_intercept_for_msr() in other vmx-specific files (e.g. pmu_intel.c),
so expose it to passthrough LBR msrs later.
