Subject: [PATCH v13 02/10] KVM: x86/vmx: Make vmx_set_intercept_for_msr() non-static and expose it
Date: Sun, 26 Jul 2020 23:32:21 +0800 [thread overview]
Message-ID: <20200726153229.27149-4-like.xu@linux.intel.com> (raw)
In-Reply-To: <20200726153229.27149-1-like.xu@linux.intel.com>
It's reasonable to call vmx_set_intercept_for_msr() in other vmx-specific
files (e.g. pmu_intel.c), so expose it without semantic changes hopefully.
